Summer’s here, but you’re missing your math? Don’t despair – we’ve got you covered. Check the site each week for one whopper of a word problem that’s sure to challenge!

Our final problem of the summer comes from Primary Mathematics Challenging Word Problems 6 by Joseph D. Lee, published in 2006 by Panpac Education Private Limited.

The number of Jason’s cards and the number of Frederick’s cards are in the ratio of 5:8. The number of Frederick’s cards and the number of Steven’s cards are in the ratio of 4:3. If Jason has 18 fewer cards than Frederick, how many cards does Steven have?

Throwback Thursday – Bar Model Solutions – by Students

Over the summer, we thought it would be fun to run some of the most popular posts from the past. It’s always interesting to see how students’ minds work.

After the post on Assessing Bar Model Solutions went up, Beth Curran sent a message: “We just did that problem!” She agreed to share some student work:

And when the students didn’t draw a model:

I see this as a comparison problem:

5 units -> 125 students
1 unit -> 125 ÷ 5 = 25
7 units for boys -> 7 x 25 = 175 boys in all

(That’s the Thinking Blocks Model Drawing tool that allows you to insert your own word problems and solve – or you can use the pre-made questions!)
