Develop fluency with the target boards. Use the target boards to:

• recall and remember useful number facts;
• use number facts to calculate mentally;
• explain thinking and methods of calculating.
• use mathematical language correctly. Print Target Board 2

• Say each number out loud.
• Put objects on each number – check that you have the correct amount.
• Say the numbers in order.

Practise addition with the target board.

Find two numbers that total 5.

• How do you know you are correct?
• How did you work it out? Explain your thinking.
• How many pairs of numbers can you find?
• Make a list of the pairs you find.

Find numbers that total 10.

• How do you know you are correct?
• How did you work it out? Explain your thinking.
• How many pairs of numbers can you find?
• Make a list of the pairs you find.

Make up a number story to go with your pairs of numbers, e.g. 3 + 2 = 5 Digit Dog ate 3 bones for breakfast and 2 bones for dinner. He ate 5 bones altogether. How many different stories can you make?

Find other totals and make up stories to go with them.

Find the total of the numbers in the first column. How did you work it out?

Find the sum of the numbers in the bottom row.  How did you do that?

Find the column with the highest total. Which column is easiest to add up? Why?

Find the number that is double 1, double 2, double 3………..

Point at a number and say what double that number is e.g. point at 5 and say “double 5 is 10”

Problem solving with the target board

My total is 8 – find two numbers that you can add together to make my total.  Can you find three numbers to make my total?

One of my numbers is 5. When I add it to another number, my total is 7. What is my second number?

I am thinking of a number. I count on 3 and get to 8. What number did I start with?

I am thinking of a number. I doubled it to make 8. What is my number?
