Cardinality & One-to-One Quantity Matching

Mathematics & Quantitative Reasoning

Your child can touch objects one by one while counting them out loud up to 20, knowing that the last number they say represents the entire total of the group.

In real life

At breakfast, you ask for 7 grapes. Your child touches each grape once while counting, then glances at the 3 left on the plate and says, "Three more," without recounting them.
