About this game

Length or weight?

Length or weight?: 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

Some children see two strips and start counting squares. Others see a scale and start naming fruit. Length or weight? is a Kindergarten game that asks what is being compared before anything else. Six of the ten pictures show two strips starting from the same line; four show a scale holding two things, an apple and a duck, or a butterfly and a duck. Your child taps one of four sentences: lengths, weights, colors or counting objects. Five pictures make a round, read aloud, and every answer is checked and explained.

Naming the attribute comes before measuring it. A strip has a length you can see. A scale shows weight by tipping, and the heavier side goes down. Even when the strips end together, or the scale balances, the question is still about length or weight.

On the scale cards, two objects sit in the pans, and a child may tap "We count objects." There are two things, after all. Ask, "What is the scale doing?" Then praise the noticing: "You looked at what the picture measures."

  • K.MD.A.1 Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
  • 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.
