A set of four posters with clear examples of counting strategies.
The three strategies include:
Jump Strategy: The jump strategy is when you use a number line to jump in tens and ones to arrive at the answer.
Split Strategy (two versions): The split strategy is when you split a number into parts and add each part separately. This is useful for large numbers.
Compensation Strategy: The compensation strategy is when you round numbers in an equation to make it easier to solve in your head.
Add and subtract numbers within 20, using physical and virtual materials, part-part-whole knowledge to 10 and a variety of calculation strategies
Add and subtract one- and two-digit numbers, representing problems using number sentences, and solve using part-part-whole reasoning and a variety of calculation strategies
Use mathematical modelling to solve practical problems involving additive and multiplicative situations, including money transactions; represent situations and choose calculation strategies; interpret and communicate solutions in terms of the situation
Recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences

how about column addition and subtraction with carrying?
Wish I had found these sooner...
Thanks for bringing this to our attention Chloe. I believe we have now fixed the issue. Kind regards, Scott
I just downloaded this, however the file only contains the 3 posters and not the second split strategy poster....where is the new version to download?
I also agree with Emily. A split strategy poster with the above breakdown would be fabulous!
Agree with Emily
Love the posters
These are great!!! Can you please make one for the split strategy where you split the number up into tens and ones and then add it. E.g. 52 + 47 = ? 50 + 40 = 90 2 + 7 = 9 90 + 9 = 99. Could you please also make these for subtraction? Cheers, Emily
Hi Emily, we've added the second version of the split strategy. We still need to work on the subtraction set. Feel free to download the new version now!
