What this lesson shows
7 counters, and some hide under a cup. 4 show, so 3 hide: 4 + 3 = 7.
The worked example
The lesson works this one step by step: 7, 4 showing. Then your kid tries one like it on paper.
The steps
- Know how many in all
- Count the ones you see
- Count on to the total

Helping at home
Read each box aloud, with how many in all. Your kid counts the ones that show, then counts on to the total on their fingers. Play it with real cups and coins.
If your kid gets stuck
Count the ones you see, then count on to the total.
