Hopper's Lily Hops — Skip-Counting by 5s, 10s & 100s (Grade 2)

About this activity

Hopper hops across a row of numbered lily pads with one pad left empty, and the child reads the jumps between them — +5, +10, or +100, forward or backward — to find the number on the blank pad. It's a free, interactive Grade 2 math activity that runs in the browser with no account.

Skip-counting is more than reciting fives and tens — it is noticing the steady rhythm of a pattern and using it to predict. Because the empty pad is sometimes in the middle and sometimes at the end, and because one round starts on an off-multiple like 3, the child cannot rely on a memorized chant; they have to read the actual pads and add or subtract the step. That is the bridge from counting to place value and later to multiplication.

It is aligned to Common Core 2.NBT.A.2 — counting within 1000 and skip-counting by 5s, 10s, and 100s. No timer, no score — just calm, playful practice.

What's inside this activity

• Designed for Grade 2 learners (ages about 7–8)
• Common Core strand: Number & Operations in Base Ten
• Aligned to Common Core standard 2.NBT.A.2

How to play

Read the numbered lily pads and find the empty one.

Work out the +5, +10, or +100 jump (or the backward hop), then tap the number that goes on the blank pad.

Not quite? Try again as many times as you like — there is no timer and no score.

What your child practices

• Count forward and backward by 5s, 10s, and 100s along a number sequence
• Find a missing number in the middle or at the end of a skip-counting pattern
• Notice the step size between numbers and name which jump is being made
• Skip-count starting from off-multiple numbers, not just from zero

Learning goals

Skip-count by 5s, 10s, and 100s within 1000 — the focus of Common Core 2.NBT.A.2.

Use the step in a pattern to predict the number that comes next or fills a gap.

Build the counting fluency that later place-value and multiplication work rely on.
