In this lesson, we will use place value charts and Dienes blocks to help us read and write three digit numbers

In this lesson, we will use a die to create three digit numbers and then partition them in a variety of ways beyond simply partitioning hundreds, tens and ones.

In this lesson, we will order and compare three digit numbers using greater than and less than symbols, number lines, and placing numbers from a table in ascending order of size.

In this lesson, we will add and subtract with three digit numbers, we will also add and subtract with regrouping. We will compare the effect of adding and subtracting ten and one hundred, using Dienes blocks and place value tables to help us.

In this lesson, we will round both 2 and 3 digit numbers to the nearest 10. We will learn how to construct and use number lines appropriately to help us as a visual aid

In this lesson, we will put on our investigation hats in order to find all the possible numbers that could have been rounded to a multiple of ten.

In this lesson, we will round 3 digit numbers to the nearest 100. We will learn how to construct and use number lines appropriately to help us as a visual aid.

In this lesson, we will investigate how to create the various 3 digit numbers with specific properties from the numbers 0-9, such as the largest odd or even number, or a multiple of 5.

In this lesson, we will use our knowledge of place value to solve different worded problems where we will have to select numbers that have certain properties from a set.

In this lesson, we will consolidate our understanding of place value, addition and subtraction from the previous lessons.
