Description
A ten-page set that goes past plain sums into how numbers behave. Alongside two-digit addition and subtraction it teaches that the order of addition does not change the answer, and that grouping numbers differently gives the same total, using bracketed sums the child completes.
Other sections ask them to compare two sums with greater than or less than signs, continue number patterns going up and down, and work backwards to find a missing number when the answer is given.
This version carries the questions only, with no answer key printed, so it can be handed out as a test or timed practice.
