Maths DLO decimals

In Te Ngahere we have been learning multiple maths strategies for adding and subtracting decimals e.g 6.4 + 7. 2 or 9.7 - 5. 9. When we had got the hang of all of these strategies we made a maths DLO based on it. We were trying not to use Place Value on a few strategies because that is most of our go to strategy. The strategies I used for my DLO was Rounding and Compensating, Equal Additions, Jumping the Number Line and Place Value. Equal Additions only work on subtraction which I think is weird because subtraction and addition are the complete opposite of each other. So how Equal Additions works is if the question is 5.8 - 3.9 = you would add .1 to the 3.9 making 4 and because you did that you have to d the same to the 5.8 making 5.9 so now the new question is 5.9 - 4 = 1. 9. I enjoyed doing this DLO because I’ve now got the hang of DLO’s now because it usually takes me ages to complete a DLO. What I didn’t enjoy was one of the activities we did which was us having to do an exercise (not physically). The exercise was we had to figure out how many ways a boy could walk to school and how many kilometers are. When we had done that we had to add up all the kilometers from each day and double that because he also had to walk back.
