Multiplication – 2D by 2D Children need to understand: 10 x 10 = 100 Tens by tens give hundreds

Multiplication – 2D by Tens 2 37Multiply 4 tens by 37 x 4 tensWhat do we do first? The ones 804 tens by 7 ones is 28 tens which is 0 ones, 8 tens and 2 hundreds Record the ones, tens and the hundreds 2 37What do we multiply next? The tens X 4 tens4 tens by 3 tens is 12 hundreds and hundreds is 14 hundreds

Multiplication – 2D by 2D 3 46What do we multiply first? x25The ones. 05 sixes is 30 – 3 tens and 0 ones Record the 0 in the ones column and 3 in the tens column.
