Addition Worksheet

Addition with Post Office — Kindergarten

Kindergarten Operations & Algebraic Thinking Common Core

On this sheet the child meets a picture and a number on the same line. They count the group of letters, stamps and a parcel, look at the number printed next to it, and count on from the pictures until the written number has been added in full. Keeping one side as a countable group of post gives a child who is still shaky on written numbers a concrete place to start, while the printed numeral gently introduces the symbol that will carry their maths later on.

Adding a group you can count to a number you can only read is a real milestone for a five-year-old. It is where counting-on begins — starting from the written number and carrying on through the pictured post — and where a child first feels that a numeral is just a quick way of writing an amount they could have laid out as objects.

Children who like post office settle into this quickly, and it suits a calm independent task or a counting game on the board. When the numbers feel easy, count a fresh group in addition with reptiles and amphibians, or try addition with things that fly. You can also browse every addition worksheet or the whole post collection for kindergarten — each sheet prints cleanly in black and white or plays online for free.
