Key Lime Pie, Muscles & More

Preparing key lime pie with little helpers, I realized our taste buds and our handwriting skills would benefit from our efforts. Little fingers reach for half a key lime, then squeeze citrus juice into a bowl, a perfect way for our littles to help prepare treats in the kitchen and strengthen fine motor skills needed to write. Thirty-five key limes later, we were ready to mix--another opportunity to strengthen muscles!

We strengthened muscles but we also built conversation skills and did a little learning. Here is what we did:

• We compared the size, color, and taste of key limes to oranges, limes, grapefruits, and lemons. Order by size. (Math, Science)
• Defined and discussed spheres in regards to the citrus. Found other spheres around the house.
• Measure the circumferences of several types of citrus with a string. Then measure the strings on a ruler to compare circumferences. Lay strings in order, shortest to longest. (Math)
• Count the fruit sections of an orange, lime, key lime, grapefruit, and lemon. Are they the same or different? (Math, Critical Thinking)
• Read the book Each Orange Had 8 Slices, Paul Giganti, Jr. 
• Draw still life pictures of the fruit, practicing shading techniques. (Art)
• Set the oven at 375 degrees. Write the temperature on a piece of paper using numbers and degrees symbol. (Math)
• Set a kitchen timer for the length of time the pie will bake. Write the ending time on the piece of paper with the oven temperature.(Math) 
• When the pie cools, discuss the definitions of diameter and radius. Measure the diameter of the cooled pie. Divide by 2 to find the radius. (Math)

Math in Our Lunch

We've encountered math in our lunch! Amazing how the best math lessons seem to happen spontaneously. How, you ask? Here are some examples (with some added extras for the adventurous):

• Cut deli-sliced cheese and meat into equal parts. Discuss halves, quarters, thirds. Write the fractions (to extend to the symbolic representation).
• Cut a sandwich in two equal pieces. Discuss equal and half. Write the fraction. Older children could cut sandwich into fourths. Discuss equal fractions and introduce adding fractions with like denominators.
  
• Cut rectangle slices off the end of a rectangular prism of cheese. Find other rectangular prisms in the kitchen (boxes of crackers, cereal, tea bags, etc.).
• Identify additional solid figures (cubes, cones, spheres, and cylinders). Compare to geometric shapes: circle, rectangle, square, triangle, and oval.
  
• Cut each rectangle slices of cheese into two squares and placed on a circular cracker. Find other squares and circles around the house. Look for right angles. Discuss straight and curved lines. Estimate the circumference of the cracker. Write the number to represent the estimate. Measure circumference of the cracker with a string and then measure the string with a ruler. Write the actual length and find the difference between the estimate and the actual.
  
• Measured the height, length, and width of the faces of the cheese block. Older children could calculate the volume.
• Discussed right angles, sides, angles, faces, length, width, height, circumference, diameter, and radius.

These an other kitchen math adventures are available in my Flip Three Pancakes with One Spatula book.

Bring Math to Life, Add Life to Math

The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires. ~William A. Ward

Math is one of those subjects that, for some, brings panic, fear, and anxiety -- angst at the very mention of multiply, sum, percent, or ratio. How do the emotions come to be? My guess is somewhere between the coins in a child's piggy bank and the black and white symbols of a textbook.

We love math when it applies to life and it makes a difference. Not a week goes by that one of my children doesn't climb upon a shelf to retrieve a bank and count the contents. For the older ones, math makes a difference when the stock market dips or real estate stagnates. Life is full of math.

Lately, life has dished us plenty of math. Is the birthday cake big enough to feed the guests at the table? How M&Ms can I pull from the bag before I get a red one? How much did each individual hanger cost in the BONUS pack of 20? How many mission trip support letters could be mailed for $10.25? When math makes a difference, it is understood. When math is understood, it makes a difference. This cycle inspires further learning.

Over sixteen years of homeschooling, we've brought math to life and we've added life to our math. Math for our children is real -- concrete -- part of everyday life. There is no panic, no fear, no anxiety. We live it. We get it.

How can you bring math to life, add life to math? I've included some of our favorite math activities in Flip Three Pancakes with One Spatula. But there is more than math. There's language arts, science, social studies, and art. To bring math to life, it most be woven into living. For example, a child could create clay spheres or they could help mom make meatballs. Then a spherical orange can be cut into equal parts and then squeezed to make orange juice. Reading Each Orange Has Eight Slices by Paul Giganti reinforces fractional concepts. That's flipping three pancakes with one spatula, and that's bringing math to life.

Taking Math on the Road

I am ecstatic about my newest resource, Taking Math on the Road! It is the first, of what I hope will be many, activity folders in my new Do, Learn, & Remember series. As children create an activity folder, they pull math off flat paper and apply concepts—numeration, graphing, measurement, computation, money, estimation, and more— to life experiences.

This series was conceived as I answered questions from parents: "How do you teach math?" or "Do you have a template for that activity?" The Taking Math on the Road CD contains instructions and templates for the games we play in our home to learn math. The CD can be purchased at my website and inserted in the CD drive of your computer. Print the pages you need and begin a thematic math adventure.

Want to know more? I am posting the introduction to Taking Math on the Road here so you can become more acquainted with the ideas behind the Do, Learn, & Remember series.

"The contents of this activity folder are intentionally written to help you teach your child math concepts. Working through this seven day study, your child will create a folder packed with high-interest activities. Unlike worksheets which teach math on a one-dimensional surface, Do, Learn, & Remember actively involves your child. The games are intended to provide stand-alone math instruction but can be easily adapted or incorporated into existing home studies.

Do, Learn, & Remember encourages mastery through repetition, an essential element for teaching math concepts. The completed folder’s compact, pocket-design keeps supplies and pieces safely inside and invites your child to carry learning through the day, playing and practicing again and again. This study is not a once-and-done-creation.

Do, Learn, & Remember activities offer flexibility. The unit was written for varied developmental stages and educational philosophies. Simply choose appropriate activities from the selections provided. Feel free to shorten, lengthen, substitute, or omit activities to accommodate your child’s learning needs. Web resources (marked with a computer symbol) and book suggestions are included for extended study. It is even possible to use the games and resources without constructing the activity folder.

Each lesson includes practical application experiences and related book titles (a library visit enhances study, but is not required) in an effort to make learning relevant to life. Additional supplemental activities and templates are available on this CD. Create, teach, and learn by the means which best encourage learning in your home.

Taking Math on the Road was tested in our home. If it didn’t work, I didn’t include it. In fact, only activities which earned a “Dad, look what we did!” made their way into this unit. Most of the activities were completed at multiple levels (ages 4-8) and some were selected as review activities for children who needed extra practice. Generally, we all played together. Our activity folder and the memories we made creating it, are treasured. We hope yours will be, too!"

Math concepts taught and reinforced in Taking Math on the Road:

• Shape and color recognition
• Counting to 100 by twos, fives, and tens
• Greater than and less than to 100
• Ordering numbers 1-100
• Ordering numbers 100-1000
• Graphing and tallying

Bonus! activities and templates for Place Value Pasta, Add the Wheels, Traffic Sign Criss-Cross, and Roman Road Dessert.

Melon Balls: How our Lunch Shaped Up

I've missed blogging, sharing stories from our life. Many weeks have passed, many blogs I wanted to write, but didn't have time to type. Maybe you will hear those later.

Today, however, math jumped out of our watermelon. Our oldest daughter was helping prepare lunch. She pulled the watermelon out of the fridge as the other daughter yelled, "Let's make melon balls!" Perfect. The younger children hadn't heard of melon balls. We took turns balling the melon into spheres of all sizes and density. Soon we have a whole bowl full of spheres and began thinking of other spheres we knew: globes, soccer balls, baseballs, soap-on-a-rope, golf balls. eyeballs. Our list ran long;the gears in our minds, spinning. By the time we made and ate 50 melon balls (counting by ones and then tens) we understood the concept of "sphere".

Learning while preparing and eating food is what my book Flip Three Pancakes with One Spatula is all about. Each lesson teaches a math concept and then extends the lesson to content areas, suggesting titles of books for additional practice or reinforcement.

So, in keeping with the concept of "sphere", here are ways to extend and reinforce the lesson.

1. Round up an orange, either off the tree, fresh off the orange tree in the backyard or from the fruit basket. Compare its spherical shape with the shape of a flat one-dimensional circle. Discuss the differences. Find examples about the house or on a nature walk. Read Circles Around Town by Nathan Olson or Circles by Sarah Schuette.

2. Cut the orange in 8 slices and divide evenly (if possible) among those at the table. Discuss the orange in terms of its fractional parts: half, quarters and eighths. Read Each Orange Had 8 Slices: A Counting Book by Paul Giganti, Jr.

3. Use a set of fraction circles to experiment with fractional parts of a circle. Cut out your own fraction circles from construction paper.

4. Measure the circumference of the orange with a string. Measure the circumference of other spheres in the home (golf ball, baseball, or beach ball). How does the circumference of the orange compare in length with the other spheres?

5. Make fresh squeezed orange juice.

6. Discuss the nutritional value of oranges. Hint: think Vitamin C, scurvy and the like.

7. Visit an orange packing plant or grove.

8. Draw and shade an orange, talking about light, dark and shadows. Research shading on the Internet, with a parent's supervision, of course.

9. Read Sunny Numbers: A Florida Counting Book by Carol Crane.

10. Mix red and yellow paint to make orange. Add black and white to make shades and tints. Use the paints to sponge paint with circles or to paint an orange, shaded with the tints of orange paint.
