2nd grade math · Unit 10: Data

One picture can stand for more

What this lesson shows

Fixes a mistake

When one picture means 5, 3 pictures are 15, not 3.

The worked example

The lesson works this one step by step: chocolate 15, plain 25, strawberry 10, key 5. Then your kid tries one like it on paper.

The steps

  1. Read the key first
  2. A picture can be 5 or 10
  3. Count by the key

Helping at home

A picture is not always 1. Read the key, then count each picture by what it stands for: 3 pictures of 5 are 5, 10, 15.
