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.
