MULTIPLICATION WITH LARGE NUMBERS
2 x 400 = 3 x 50 = 900 x 4 = 30 x 5 = 80 x 2 = 700 x 3 = 4 x 300 = 9 x 90 = Start with easy numbers like 2 x 4. Then decide whether to multiply that by 10, 100 or 1000.

DIVISION WITH LARGE NUMBERS
1. 80 2 = How many 2s in 8? ……. How many 2s in 80? ……. 3 = How many 3s in 12? .….. How many 3s in 120? …… 4 = How many 4s in 20? ….. How many 4s in 200? ….. 2 = How many 2s in 6? ……. How many 2s in 60? ……. 3 = How many 3s in 18? .….. How many 3s in 180? …… 4 = How many 4s in 16? ….. How many 4s in 160? …..
