**Numberblocks **– Build concepts of composing, decomposing, adding, subtracting. Unfix Cubes are suggested to go along with this. Can be done with a whiteboard, but the hands on building is important.

**One** – Learn to count to five using the number one.

**Two** – Add and subtract 1 to make number 2 bigger or smaller.

**Three** – Learn all about three including three 3’s is 9.

**One, Two, Three** – Adding with all three.

**Four** – Decompose 4 by the terrible twos. Introduces square. Two 4’s is 8.

**Five** – Decompose 5 to 1 + 4 and 2 + 3. Also 1+1+1+1+1.

**Six** – 6+1 is 7. 3 + 3 is 6.

**Six, Seven, Eight** – Dice/die, 6+1, 7+1, twos to build 8.

**Nine, Ten** – count to 9, 3 threes is 9 like 2 twos is 4 = squares.

**Ten** – Count to ten and decompose, place value.
