How to help

Mark each picture with a small tick as you count it, so you can see which are done. Work across in rows. The last number you say is how many.

Watch for: Counting some pictures twice when they're spread out. Missing pictures near the edges or tucked between others. Saying the teens out of order, like 13 then 15.

At home: Spill up to 20 pieces of dry pasta or cereal on the table. Your child counts them, sliding each one aside as it's counted.
