Kavi's Twin Pond 💧
Kavi peeks into the still pond — every acorn on the bank has a twin in the water 🌰! "3 and 3 is a double: double 3 is 6!" Then one extra acorn plops in. "3 and 4 — a near-double, so double 3 plus 1 more: 7!"

What your child will learn
1Two equal rowsA ten-frame has two rows of 5. Tap Add 5 to fill the top row: the full row and the empty row are exactly the same — 5 + 5 = 10.
2Two matching partsSplit a number into two parts. When both parts are the same, you have a double — like 8 = 4 + 4. All the doubles to 10: 1+1 · 2+2 · 3+3 · 4+4 · 5+5.
3Almost a doubleSplit 9 into 5 and 4: the parts are only 1 apart — a near-double. Think: double 4 is 8, plus 1 more makes 9. Near-doubles to 10: 1+2 · 2+3 · 3+4 · 4+5.
4Say them fastNo pictures now — just know them. The bright numbers are the answers to the doubles: 2, 4, 6, 8, 10.
