Today during maths and morning tea I did some new maths problems. Personally I think that I picked it up quite fast, considering that I had never heard or used this tactic before. Anyway here are a few of the 14 I did that I feel particularly proud of.

1. 14 x 5 = 70

1. Split the 14 into 10 and 4

2. 10 x 5 = 50

3. 4 x 5 = 20

4. 50 + 20 = 70

2. 36 x 4 =144

1. Split the 36 into 30 and 6

2. 30 x 4 = 120

3. 6 x 4 = 24

4. 120 + 24 = 144

3. 57 x 8 = 456

1. Split the 57 into 50 and 7

2. 50 x 8 = 400

3. 8 x 7 = 56

4. 400 + 56 = 456

4. 29 x 8 = 172

1. Split the 29 into 20 and 9

2. 20 x 8 = 160

3. 9 x 8 = 72

4. 160 + 72 = 172

5. 91 x 3 =

1. Split the 91 into 90 and 1

2. 90 x 3 = 270

3. 1 x 3 = 3

4. 270 + 3 = 273

All and all I feel amazed at my change of attitude. I got 14\14! I am very proud and impressed with myself.
