Show a seven-year-old two boxes of dots and many will count every dot from one, even when the first box clearly holds three. This 2nd grade dot model addition sentences worksheet asks for something quicker: see each part, then see the whole. On the left, six models line up, each one a small box of dots, a plus sign, a second box and the total. On the right, six addition sentences wait in blue frames, from 1 + 2 = 3 to 5 + 5 = 10. Your child draws a line from each model to the sentence it describes. The sums up to 10 keep the arithmetic light, so attention goes to reading the model. A second page gives the answer key.
