Today in class we were doing maths and this is what my maths group did today.
WALT: Multiply by whole 10’s and 100’s.
1.
10 x 315 = 3,150
3,560 x 10 = 356,000
35 x 100 = 3,500
2.
100 x 6,200 = 62,000
10 x 1,200 = 12,000
100 x 130 = 13,000.
3.
1,00 x 250 = 25,000
38 x 1,000 = 38,000
10 x 5,000 = 5,000
Multipying by 20 and 200
1.
20 x 8 = 160.
4 x 20 = 280.
20 x 5 = 210.
2.
200 x 7 = 14,00.
5 x 200 =1,000.
20 x 5 = 100.
3.
20 x 7 = 140.
35 x 20 = 700.
200 x 9 = 18,00.
4.
20 x 16 = 132.
42 x 200 = 42,00.
