# Year 3 Autumn Term: Block 1 Number and Place Value

Building on the work done in Year 2 children will understand what 100 is and count in multiples of 100 up to 1000. They should also understand that a 3-digit number is made up of 100s, 10s and 1s and read and write 3-digit numbers. Place value grids and an abacus are great ways to help with this.

Number lines are still really useful, especially when putting numbers in order and estimating.

Children will move on to finding 10 or 100 more or less than a number and they will also compare 3-digit numbers and order them from smallest to largest.

Being able to confidently count in fives will help with counting on and back in fifties.

This work on number continues for the first three weeks.
