Count Out the Money — Coins to a Target Amount (Grade 2)

About this activity

This free, interactive measurement activity helps young children compare objects by size — taller, shorter, and longer — without any counting. It plays right in the browser on tablets, phones, and classroom computers, with nothing to install and no account needed.

It is aligned to Common Core 2.MD.C.8 in the Measurement & Data strand. Children compare at their own pace with gentle, immediate feedback — no timer, no score, just playful practice looking closely at how things measure up.

What's inside this activity

• Designed for Grade 2 learners (ages about 5 to 9)
• Common Core strand: Measurement & Data
• Aligned to Common Core standard 2.MD.C.8

How to play

Children look at two pictures of the same object shown at different sizes and read or listen to the prompt.

They tap the one that is taller, shorter, or longer, depending on what the prompt asks.

A warm check confirms a correct choice and offers an easy retry when needed.

What your child practices

• Comparing two objects directly by a measurable attribute like length or height
• Deciding which object is taller, shorter, or longer
• Describing the difference between two sizes in their own words
• Looking closely and reasoning about size instead of counting

Learning goals

Directly compare two objects by a measurable attribute — the focus of Common Core 2.MD.C.8.

Use the words taller, shorter, and longer to describe and compare sizes.

Build the early measurement vocabulary that later length, weight, and data work rely on.
