Mathematics & Quantitative Reasoning
Your child can skip-count perfectly by 2s, 5s, and 10s. They can confidently add and subtract single-digit numbers (numbers 1 through 9) and understand how to add tens together (like 20 + 30).
In real life
Your child climbs the stairs counting by twos: "2, 4, 6, 8, 10." Later, with 7 apple slices on the plate, they eat 3 and say, "Four left."
