About this game

How can we compare?

How can we compare?: a free Kindergarten math game for ages 5-6. Each round draws 5 questions; instructions are read aloud and every answer is checked and explained.

How it plays and why it helps

Which bag of groceries is heavier? Children often lift both, then guess by size. How can we compare? is a Kindergarten game about choosing the method before the answer. Each question names two things, bags, benches, pencils, ribbons or boxes, and asks how we should compare them. Your child taps one of four plans, such as weighing on a scale or laying them side by side from the same end. The same five cards come in every round, read aloud, and each answer is checked and explained.

Measurement starts with knowing which quality you are looking at. Length can be seen when two things start together. Weight cannot be seen at all. The bench card adds a clever idea: when objects cannot move, a string carries one length over to the other.

On the weight cards, look out for "We just look at their size." It sounds sensible, yet a big box can be light. Ask your child, "Can your eyes feel heavy?" Then praise the plan: "You picked a way to find out."

  • K.MD.A.2 Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.
