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

Goal Setting in Addition and Subtraction

My goal in addition and subtraction is to: use my strategies for percentages.
