Problem Solving

W.A.L.T: solve maths problems using place value and basic facts

How many different ways can you write...?

679

600+70+9. 600 ones 70 tens 9 ones. 670+9. 600+79.
779-100. 67 tens 9 ones. 679 ones.

I found this activity rather easy with my buddy Grace.

Can you think of a different way to solve this???
