LO: To know how to subtract with 2-digit numbers.

 

Today we are going to continue with subtracting a 2-digit number from another 2-digit number using a different method.

 

You will need a pencil and square paper, your number square will also be helpful if needed (to help counting in tens).

We are going to partition numbers to help with working out the answers.

Let’s try another one:

 

 

 

Have a go at these, then check the answers.

 

34 – 12 =           35 – 15 =       27 – 16 =      29 – 18 =      46 – 24 =

 

39 – 17 =         48 – 24 =         36 – 14 =       47 – 25 =     48 – 31 =

 

 

If you found these ok, have a go at these:

 

68 – 32 =      87 – 45 =       66 – 33 =    59 – 34 =
