Solving Subtraction Equations & Maths Game

L.I: To use the standard written form to solve addition and subtraction problems.
L.I: To carry out colum addition and subtraction with whole numbers of up to four digits.
This week for inquiry we learnt a a new game. We had to create a DLO making a digital version of it and create a screencastify to show how it works. We also had to solve 4 subtraction equations using standard writing form. In the screencastify I explain to you how to play and what you need to play. The 4 subtraction equations we had to solve were - 45 -17, 234 - 167, 1234 - 987, and 23.4 - 16.7.

Simple Maths Strategies

L.I: To learn and understand how to solve addition and subtraction problems using place value.
This week for maths we had to create a DLO showing different simple maths strategies explain how you have done it. On my DLO I have shown you 4 different ways you can solve the equation - 49 + 36 and how to prove that it does equal 85. The first strategy is the Number line and I explain to how I do that, the next strategy I did was the Number bond strategy and I explain I how I use it to solve the equation, the next strategy was the Vertical maths strategy and I also did an explanation for that as well, the last strategy was the Place value strategy and just like the rest of the strategies, I explain how I do it.
