Tell a seven-year-old that a boy scored 427 points on Friday and 512 on Saturday, and they will want to know who won. Turning that curiosity into math is the whole job of this 2nd grade 3-digit addition word problems worksheet. The page holds three stories. Brooks plays a video game over three days, and three short questions ask which two days to put together. Next, 496 dogs join the 216 already at an animal shelter. Finally, Miss Mary sharpens 87 pencils on Monday and 100 on Tuesday. For each one, your child writes an addition sentence, not just an answer. A second page gives the answer key.
