Pippa's Pond-Juice Lab — Pour and Read the Measure

About this activity

Pippa the frog runs a pond-juice stand where a customer orders by feel — "a dragonfly wants about six cups!" — and the child pours into a frosted beaker, then taps Pour or Look to reveal where the juice really landed on a 0-to-10 scale and taps that number. It's a free, interactive Grade 3 measurement activity that runs in the browser with no account.

The activity is built so reading the scale is the only thing being judged — not how carefully you pour. The level stays invisible during the pour, so there is no line to chase, and the answer is the revealed level, never the order: when the customer asks for 'about six' but the juice reaches 5, tapping 6 is wrong. Some rounds show two beakers — including a tall-thin one beside a short-wide one, or scales that go to 10 next to one that goes to 20 — so the bigger-looking cup is not always the one with more; the number decides.

It is aligned to Common Core 3.MD.A.2 — measuring and estimating liquid volumes using a scale. No timer, no score — just calm, playful practice.

What's inside this activity

• Designed for Grade 3 learners (ages about 8–9)
• Common Core strand: Measurement & Data
• Aligned to Common Core standard 3.MD.A.2

How to play

Read the order, then tap Pour or Look to reveal where the juice reached on the scale.

Read the number the juice reaches and tap it on the strip — or, with two beakers, tap the one that holds more.

Pour and serve another glass; there is no timer and no score, so you can read carefully each time.

What your child practices

• Reading a liquid level off a numbered measuring scale, mark by mark
• Telling an estimate ('about six') apart from the real measured amount
• Comparing two amounts by their scale numbers, not by which container looks bigger
• Reading scales that count by ones and by twos, including to 20

Learning goals

Measure and estimate liquid volume by reading a scale — the focus of Common Core 3.MD.A.2

Understand that the measured level, not a guess or a container's shape, gives the amount

Build the careful scale-reading habit that later measurement and data work depend on
