Addition and Subtraction Strategies Rubric Term 3 2021 Name:
Criteria | Level 2 (5ii) | Early Level 3 | Level 3 | Level 4 |
Addition and Subtraction strategies | Simple strategies to add and subtract smaller numbers. | Knowing a range of strategies e.g. use of an algorithm, or partitioning. | Applying a range of appropriate strategies for different problems. Number lines, compensation, | Have a range of strategies that can be used for decimal numbers and fractions |
My goals:
Goal | Success Criteria (This is what it will look like when I get there) |
I need to be able to break numbers up to make it easier to subtract.
| To achieve this goal I can break up single digit numbers to add or subtract. Eg 47 + 8 means 47 (+ 3 + 5) = 47 + 3 = 50 + 5 = 55 or in 43 - 6 the 6 would be partitioned into a 3 and a 3. 43 - 3 = 40 - 3 = 37. |
I need a range of strategies to be able to use to add and subtract when solving different problems | To achieve this goal I can use different strategies. I can use numberlines to count on and count on back, rounding skills to compensate as well as an algorithm. I must be able to partition well so I can bridge through tidy numbers. |
I need to be able to select the strategies to use to add and subtract when solving different problems |
To achieve this goal I will have a range of different strategies I can use. I can look at numbers in a maths problem and say this strategy will be best here because ……… I need to be able to justify and explain. I begin to check my answers. |
I need to be able to extend my use of addition and subtraction strategies to decimal numbers, fractions, and percentages. | To achieve this goal I will be able to solve math problems that involve decimal numbers, fractions. I will use self checks and inverse to help my accuracy |

Addition and Subtraction Reflection
Using the two tests, think about your strengths and which gaps you have sorted out. (goals you have achieved). Google form to be completed at the end of the 3 weeks.
Talk to someone about:
How you achieved them (you could talk about how quickly you achieved them, some of the learning qualities that helped you achieve them.)
What strategies you now have to help you with addition and subtraction problems. (use your rubric)
What worked well for your learning (what you did or what your teachers did)
What could have been better (what could you have done better? or what could your teachers have done better?)
My reflection
My goal was to have a range of strategies that can be used for decimal numbers and fractions. I think I have achieved my goal and now I am onto the next step. I did not get the last problem right but everytime I see it I will remember it and so I don’t really have any problems. I would also like some mathletics problems involving the last problem. I also would like to do another one and try to get it right.
