Kindergarten addition, kept deliberately small: both numbers run from 0 to 5, so every sum lands at 10 or below and the whole problem can be worked by counting on fingers. Twenty problems fit on a page - a full sitting for this age without being a page a five-year-old gives up on.
One operation only. Subtraction and the mixed pages start in first grade; a kindergarten sheet that switched between adding and taking away would be asking for a distinction this year has not drawn yet. When addition within 5 is steady, the 1st Grade page opens it up to 0 through 9 and brings subtraction in.
Counting to 100 by ones and tens, counting objects to 20, comparing two written numbers, and adding and subtracting within 5 fluently. These sheets cover the addition; the hundreds chart covers the counting.
Adding within 5 is the kindergarten fluency goal, and staying there means every problem can be checked on fingers. Raise it by ticking more numbers in either value range above.
It is about right for a sitting at this age. If it is too long, switch Half Page on and each sheet becomes two shorter worksheets to cut apart.
