Track Zero maths: seven number ideas to carry into Class 6
IdeaWhat to remember
CountingTouch each thing once. The last count word is the answer.
Number lineEvery number has one spot, in order. Zero is first.
Place valueA digit's place tells what it counts. Ten ones make a ten.
ComparingMore digits is bigger. Same digits? Compare from the left.
ZeroIt can mean none, or hold a place.
ShapesCount corners and edges. Turning does not change a shape.
× and ÷× counts equal groups. ÷ shares. A leftover is the remainder.
