Kavi's Bundles of Ten 🥢
Kavi the owl is counting straws for craft day. Instead of counting one straw at a time, Kavi ties them into bundles of ten — then counts the loose ones left over. "4 bundles and 7 singles," hoots Kavi. "That's 4 tens and 7 ones — forty-seven straws! Every two-digit number is just some tens and some ones."

What your child will learn
1A number is tens + onesThe whole number sits on top; the two parts below are its tens and its ones. Here the whole is 47 — one part is the 4 tens (40) and the other is the 7 ones (7).
2Make sixty-threeNow try 63. Use ◀ less and more ▶ to stop where the first part is a tidy ten — the 6 tens (60) — and the second part is the ones (3).
3The tens ladder to 100The bright numbers are the pure tens: 10, 20, 30 … 100. Every two-digit number sits just after one of these, with its ones added on.
