This week in Maths we have worked on subtraction.
In subtraction we had to do number lines, regrouping and jumping strategies. For the number lines we had to take away a number and we had to find the best jumping strategies. For subtraction we went on a website called maths online and did three-seven digit numbers and we also had to do five sums in take away.
Regroup is when you are doing a subtraction sum if you had three thousand take away two thousand and six hundred then for the hundreds you can’t take away six from zero you have to get a hundred and then it becomes three thousand and ten hundred so you take away six from ten then it becomes four hundred.
