In the summer, Costco peddles a buttload of educational workbooks. You know the ones: collections of every worksheet necessary for your child to complete <insert grade here> Math. Can’t find them? Look over by the Christmas trees.

I picked up the Grade 3 book. Just browsing. Killing time. I opened to this page:

I’m not a big fan of this approach. Forget about comprehension, just scan for the add or subtract words. See *more*, think *add*. But it’s not that easy. *More* shows up in five of the practice exercises. Try them.

- In the picture, how many
**more**4-legged animals are there than 2-legged ones? - Peter has 39 goats. He wants to have 64 goats. How many
**more**goats should he buy? - Peter has 68 animals on his farm. He buys 23
**more**. How many animals does he have now? - 413 gulls are joined by 311
**more**. Then 136**more**gulls come. How many gulls are there altogether? - There are 576 gulls, but 153 fly away. Then 283
**more**leave. How many gulls remain?

A mountie (really?!) tells kids (Canadian, no doot) to decide on the operation.

From the answer key:

- In the picture, how many
**more**4-legged animals are there than 2-legged ones?**15 − 12 = 3** - Peter has 39 goats. He wants to have 64 goats. How many
**more**goats should he buy?**64 − 39 = 25** - Peter has 68 animals on his farm. He buys 23
**more**. How many animals does he have now?**68 + 23 = 91** - 413 gulls are joined by 311
**more**. Then 136**more**gulls come. How many gulls are there altogether?**413 + 311 + 136 = 860** - There are 576 gulls, but 153 fly away. Then 283
**more**leave. How many gulls remain?**576 − 153 − 283 = 140**

Subtraction is used to answer three of five questions with this ‘add’ word. Actually, kids *will* think addition for the first two questions (12 + 3 = 15 and 39 + 25 = 64) but that’s another post.
