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.

Place Value House

L.I: To show how to use place value to solve a subtraction equation using - ten for one and one for ten.
This week for maths we had to create a DLO showing an example of us using place value for subtraction. We learnt about the phrase - tens for ones and ones for tens. Ten for ones and ones means that 1 ten is that same as 10 ones and 1 one hundred is the same as 10 tens, so basically if you transfer a higher number in to a different number it will always be a ten or one. Like say if it was 100 which is a higher number, if you transfer into a different number digit like the tens it will still be one hundred but seem as 10 tens. I created my DLO and learning for this on a google draw. We had to first watch a video of someone showing us how to subtract using a place value house. After watching the whole video, we just went over again some of what she said and a few examples with the teacher. I learnt today that you can subtract using a place value house. My equation was 325 - 127. In the google draw I explain how I did it and show you what I did. I also included what is ten for one and one for ten.

Maths Strategies

L.I: To show different ways and strategies to solve subtraction and addition problems.
This week for maths we had to create a DLO showing different ways we can solve subtraction or addition equations. I created a Google presentation because it would be the best and appropriate one to use. We were given two subtraction questions to solve, and they were: 783 - 395, and 1123 - 846. I showed 4 ways to solve them - Place Value, Number Line, Reverse operation, and Algorithm. My favourite strategy to use is the Place Value.

Fractions: Add & Subtract

L.I: How to add and subtract fractions that have different or same denominators.
This week for maths we have been learning how to add fractions with different denominators and how to subtract fractions with different denominators. We had to make a copy of a google doc which had a list of addition and subtraction fraction questions and we had to put what the answer is in fractions and what the answer is in mixed numeral if it had one. To help me with the a few of the questions I used a white board and figured it out on there or I used pencil and paper. I learnt to subtract fractions also fractions with different denominator and add fractions that have different denominator.
