Most kindergarten maths practice is a worksheet wearing a smile. This is not that. Hannah Whately, an elementary teacher and maths education specialist, built one hundred puzzles and activities that hide the practice inside something a five year old actually wants to finish.

It covers the whole kindergarten spine: counting and number recognition, simple addition and subtraction, shapes and patterns, and first measurement. Because each page is a puzzle rather than a row of sums, a child who has stalled on drills will often keep going here without noticing that they are doing the same maths.

144 pages from Adams Media, big and bright, and it works equally well as classroom support, summer catch up, or the thing you hand over in a restaurant when the crayons run out. For a household with a four to six year old, it is one of the highest value nine dollar purchases on the shelf.
