Practise using reordering strategies with these extra E2 (E1 questions are in a separate Wordwall activity) questions for our recently updated E1-E2 Mental addition strategies (reordering) PDF worksheet (Maggie Harnew, 2005, updated Feb 2022). Match the correct answer to each addition problem. (Reordering involves adding up large numbers first and/or looking for pairs of numbers that add up to 10, 20, 30, etc.). Can be used independently of the original resource.
A great way to start a class – provides mental maths practice for E2-E3 but also suitable for higher level learners who can try it out with with large numbers and discuss how it works!
