First Grade – Major Works of the Grade
Add and subtractwithin 20 in contextual problems, with unknowns in all positions by drawing pictures, using objects and writing equations with the correct symbols. Also, adding 3 whole numbers whose sum is within 20.
*Parents can make up contextual problems at home – for example: There are 5 apples in the bowl. We ate 3 of them. How many are left?
There were 7 cookies on the plate. Dad ate some of them. Now there are 2 left. How many cookies did Dad eat?

Add a two digit number to a one digit number.
Adding and Subtracting multiples of 10
*The hundred boards from site above at mathwire.com are great for this type of practice.
