LET ME COUNT THE WAYS Multiplication

Use What you Know 8 x 6 = ? If you can’t remember the answer to 8 x 6, then use a fact you do know. Such as 8 x 5 8 x 5 = 40 then just add another = 48 So 8 x 6 = 48

Use What you Know 4 x 7 = ? If you can’t remember the answer to 4 x 7, then use a fact you do know. Such as 2 x 7 2 x 7 = = 28 So 4 x 7 = 28
