Measuring the Edible Part of an Apple: A Fun and Interactive Math Activity for the Classroom

What’s more delicious than engaging, real-world math problems? How about engaging, real-world math problems featuring everyone’s favorite fruit – the apple! In this unique math activity, we’re going to use apples as a tool for understanding and applying concepts of measurement, weight, subtraction, and percentages. This will guide you through the process, and offer accommodations and modifications to tailor the activity to different learners.

Activity Overview

Our activity is titled “Measuring the Edible Part of an Apple.” The objective is to calculate the weight of the edible part of an apple, then represent this as a percentage of the whole apple’s weight. The math skills involved are measurement, subtraction, division, and percentage calculations. As educators, we know the power of hands-on learning and concrete examples in fostering understanding. Plus, using food in a lesson never fails to pique student interest!

Materials Needed

For this activity, you will need:

  1. An apple for each student (make sure to have a few extra in case of accidents!)
  2. A napkin for each student
  3. Scales with metric units of measurement (one per group or one per student if available)
  4. Paper and pencils

Activity Procedure

Here are the steps to follow for the activity:

  1. Introduction: Begin by discussing what is considered to be the edible part of an apple. This can be a great opportunity for a mini-lesson on health and nutrition!
  2. Weight Measurement: Have students measure the weight of their whole apples using the scales. Ensure they’re comfortable using the scales and are recording the weights in grams.
  3. Enjoy Your Apple: Students now get to enjoy their apples! Ask them to eat the edible part of their apple and set aside the uneaten portion on their napkin.
  4. Post-Apple Measurement: Have students weigh the uneaten portion using the scales and record the weight.
  5. Calculate the Edible Weight: Students will subtract the weight of the uneaten part from the whole weight to find the weight of the edible part.
  6. Percentage Calculation: Finally, students will divide the weight of the edible part by the whole weight and multiply the result by 100 to find the percentage of the edible portion.

Here’s a handy table that students can use to record their measurements and calculations:

Accommodations and Modifications

The beauty of this activity is its flexibility. Here are some ways to modify it for different learning needs:

For younger learners or students struggling with division and percentages:

  • Simplify the activity by focusing only on the measurement and subtraction components.
  • Instead of calculating the percentage, ask them to visually represent the edible and inedible portions using colored pencils or markers.

For English language learners or students with reading difficulties:

  • Provide written instructions with visual aids.
  • Pair students up so they can support each other during the activity.
  • Use a document camera to show the steps of the activity in real-time.

For advanced learners:

  • Ask them to record the data for the entire class and calculate the average percentage of the edible portion.
  • Have them graph the class data, with apple weight on the x-axis and edible portion percentage on the y-axis.

For students with physical disabilities:

  • Have a peer or teacher aide assist with the physical components of the activity, such as eating the apple and using the scale.

Learning Objectives and CCSS Alignment

By the end of this activity, students will be able to:

  • Measure the weight of objects in grams using a scale
  • Use subtraction to determine the difference between two weights
  • Calculate the percentage of a whole using division

This activity aligns with the following Common Core State Standards:

  • CCSS.MATH.CONTENT.4.MD.A.2: Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money.
  • CCSS.MATH.CONTENT.5.NBT.B.7: Add, subtract, multiply, and divide decimals to hundredths, using concrete models or drawings and strategies based on place value.
  • CCSS.MATH.CONTENT.6.RP.A.3.C: Find a percent of a quantity as a rate per 100.
