Year 2/3 Addition and Subtraction
<p>I teach the lower set of Year 3 mathematicians in our school and developed these resources to help them visualise how column addition and subtraction work. We start with expanded method in year 3 as we want the children to fully understand the value of each digit.</p>
<p>The Place Value Grid is brilliant for helping children add and subtract using the column structure with Base 10. I then use the 2 diennes sheets to move them from concrete to pictorial (slightly Singapore maths linked). The other sheets are linked with STAR maths (See it, Try it, Apply it, Reason it) and I tend to use these along with try it questions on the whiteboard for the children to answer.</p>
<p>Hope you find these as useful as I have.</p>
