1st grade math · Unit 3: Tally marks and pictographs

Graphs help us predict

What this lesson shows

A picture graph of the fruit a class picked: 8 apples, 3 bananas, 5 grapes. Most kids picked apples, so a new kid will most likely pick apples too.

The worked example

The lesson works this one step by step: apples 8, bananas 3, grapes 5. Then your kid tries one like it on paper.

The steps

  1. A picture graph, a table, or a bar graph
  2. The longest row or tallest bar is the most
  3. The most picked is the most likely next

Helping at home

Read each box aloud. Your kid draws a picture graph, one face for each kid, and a table of the counts. Ask which answer most kids picked, and what a new kid would most likely pick. Try it with a family vote on dinner.

If your kid gets stuck

The longest row is the most picked.

Watch it with Lux

With Lux, this lesson is a narrated video and a printed page your kid works on. Then Lux helps with the same math on their own worksheet, one question at a time.
