Scale It Up
This lesson will allow students to demonstrate knowledge use of scale.
Grade Level: 2 - 3rd
Length of Time: 15-25 Minutes
Common Core Alignment
CCSS.MATH.CONTENT.3.MD.B.3 - Draw a scaled picture graph and a scaled bar graph to represent a data set with several categories. Solve one- and two-step "how many more" and "how many less" problems using information presented in scaled bar graphs. For example, draw a bar graph in which each square in the bar graph might represent 5 pets.
Objectives & Outcomes
Students will recreate a simple picture on a larger scale.
Pictures (sample included), colored pencils, printer paper
Opening to Lesson
- Ask students if they understand scale.
- Explain that if you are printing something on a larger scale it means you are making it bigger, but each part will be in the same area.
- Tell students you will show them a simple way to do scale.
Body of Lesson
- Give students the sample picture provided.
- Give each student only one of the pictures though several can be printed on the same page.
- Also provide students with a single sheet of printer paper.
- Have students examine the small drawing.
- Now have students fold the paper in half lengthwise and then fold it in half the other way.
- Have students do the same with the larger sheet of paper.
- Explain that they have created scale. What is on the small paper in a particular scale, can be drawn larger on the blank paper in the same square. This will create a larger scale drawing.
- Have students put drawings together to show understanding of scale.
- Allow both drawings to be colored if time permits.
Assessment & Evaluation
The students will accurately recreate a drawing on a larger scale.
Modification & Differentiation
Special needs students may be given extended time or a simpler drawing.

The lesson is used for students to practice basic time measurement, and understanding the basic units of time.
Students will compare numbers with three or more digits using visual cues.
Students will create a “pizza” from construction paper divided into 8 slices. They will decorate each slice and then exchange slices with classmates and then evaluate the fractions of slices that they have at the end. For example, 1/8 slices of my own pizza, 4/8 or ½ of pizza that was made by a female, 2/8 or ¼ that was made by my buddy. Note: Students should have already had some lessons about simplification of fractions.
Students will learn to create a small bar graph using candy for information.
