Year 2
Show the same number in different ways and estimate where it belongs on a number line.
Number - number and place value
A number can be shown with counted objects, tens rods and ones cubes, or a point on a number line. When we estimate, we make a sensible choice by looking at the numbers around it and deciding where it should go.

Estimate between two known numbers
The marker is between 50 and 60 and sits close to 60.
A sensible estimate is 58 because it is only a little before 60 and well after 50.
24 can be counted and placed
There are 24 counters altogether.
You can count the counters, then match that quantity to 24 on a number line.
What number is shown by the base-ten blocks and where would it go on the number line?
Look carefully at each representation before you answer.
Watch for these when you read or estimate a number.
These ideas fit closely with representing and estimating numbers.
