Materials:

● two clear jars

● one reference jar with 10 fruit counters

● one full jar

● whiteboard

● whiteboard marker

Step 2: Teach Lesson

Repeat the steps below with both the full jar and the jar with 10 fruit counters (the fruit counters can be replaced with other items you

might have at home).

Ask: “How many fruit counters do you think are in this jar?”

Let the student hold the jar and give aloud an estimate or guess (depending on their knowledge and experience) of how many are in

the jar.

Write the estimate on the whiteboard. Allow the student to guess any number.

When the student has guessed, ask, “How can we find out how many are in this jar?”

Dump out the fruity counters and with the student, count them back into the jar.

As you go along ask, “Do you want to change your guess?” Change the answer if the student wants it to be changed.

After counting, see if the student has correctly estimated the number of fruity counters in the jar.

Have the student complete the worksheets below for extra practice.

Step 4: Review- Start the next lesson with the game or activity attached below for review so the student can demonstrate

understanding of this lesson before moving forward.

Estimating with Nature: (offline) activity

Take your child outside to the park, a garden, or backyard. Try to spot an ant or a snail and have the student estimate how long it will

take the ant to get from Point A to Point B. Write down the students estimate, and then watch.

Balance Challenge: (offline) activity

This activity can be done alone or with other children. Teacher can also participate.

Ask the kids to estimate how long they think they can balance themselves on one foot. Have them write down their estimates, and

then do the balance challenge( you can use a watch to count the seconds or have the other kids count the seconds as the others do

the challenge. The teacher should lead in the count). The student that estimates closest to the actual number wins the challenge.
