# Counting on Frank

Keywords:
Purpose:

This is an activity based on the picture book Counting on Frank.

Achievement Objectives:

Achievement Objective: GM2-1: Create and use appropriate units and devices to measure length, area, volume and capacity, weight (mass), turn (angle), temperature, and time.
AO elaboration and other teaching resources

Specific Learning Outcomes:
1. Students will explore and compare the volume of different containers using non-standard and standard units.
2. Students will be able to explain why standard units of volume are necessary when making comparisons.
Description of mathematics:
1. To understand measurement concepts such as length, rate, or volume, it helps to create units from our everyday experience and use these to compare to standard units.
2. Estimation is an important skill in measuring and comparing attributes.
Required Resource Materials:
Counting on Frank by Rod Clement
Containers of different shapes and sizes including large boxes and jars
Objects to fill boxes and jars
Cubic centimeters from place value blocks
Rulers and measuring cups
Activity:

Frank’s Units: Estimating and Measuring Volume
This activity is based on the picture book Counting on Frank.

Summary:
Frank is a big dog and Frank’s owner has a brain and knows how to use it when it comes to numbers. Frank’s owner shares his knowledge of the size and scope of things such as the growth rate of a gum tree or the volume of the shopping trolley. It is a humourous look at measurement and comparison.

Lesson Sequence:

1. Prior to reading, make the connection to the story by pointing out the lolly jar on the cover and ask
Who has tried to guess the number of lollies in the jar?
What strategies did you use to make your guess?
Did any of you ever win?
Do you have to get the exact number?
What does estimation mean?
2. Share the book with the students drawing their attention to the times when Frank’s owner makes an estimate (like when he uses the word “about”), when he calculates (exact numbers) and when he just knows a fact. You can have one student record all the measurements on the whiteboard or modeling book as you read the story so the numbers can be re-visited at the end.
