This session uses pictorial representations to add three single digits (numbers) together. You will need to space your working out neatly on your whiteboard and remember to recount your circles to check your counting. Good luck!

Adding three single digits together

 

Using the method above, can you solve the following number sentences?

 

1)  2  + 4 + 1 =

2) 3 + 2 + 5 =

3) 3 + 3 + 4 =

4) 2 + 6 + 1 =

5) 4 + 5 + 1 =

6) 6 + 2 + 3 = 

7) 8 + 2 + 5 =

8) 5 + 5 + 7 =

9) 10 + 1 + 3 =

10) 5 + 8 + 3 =

Continuing with the addition of three single digit numbers, in this session we will use of knowledge of bonds of 10 to help us solve the problem a little easier.

Remember to spot the bond of 10 and solve that first then simple add the number that you haven't used. It might be worth writing the bonds of 10 before you start this task.

Adding three single digits - bonds of 10

 

Using your bonds of 10, can you solve the following number problems?

 

1)  2  +  8  +  3 =

 

2)  5 + 5 + 4 =

 

3)  7 + 3 + 6 =

 

4)  9 + 1 + 2 =

 

5)  6 + 4 + 9 =

 

6) 3 +  5  +  7  =

 

7)  9 +  6  +  1  =

 

8)  5  +  8 + 5 +

 

9)  9  +  2  +  8 =

 

10)   0  +    6  +  10  =
