Grade Level: 2 - 3rd

Subject: Math

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.

Materials Needed

Pictures (sample included), colored pencils, printer paper

 

Procedure

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.

Closing

  • 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.

Students will compare numbers with three or more digits using visual cues.

Fun Fraction Pizza

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.

Skittles Graph

Students will learn to create a small bar graph using candy for information.
