This Week from Bedtime Math: The Dog Ate My Homework

Excuses, excuses... but sometimes, they’re true! Try this week’s math problem to see how much trouble one hungry dog can create.
on April 09, 2013

This timeless excuse lives on as a reason for lateness, and it’s not just for kids — don’t we all procrastinate on stuff we don’t feel like doing?  And with today’s technology you can get creative, too:  “The dog ate my flash drive,” “The dog ate the cable to our wireless hub…”  It’s all believable, as long as you have a hungry dog in tow.

Of course, dogs really do like to chew things up, and some of that stuff actually could be homework-related…

Wee ones (counting on fingers): Hannah’s dog Harley eats pretty much anything.  If Harley eats 3 pens, 2 crayons, and 4 washable markers, how many writing implements does he eat?

Little kids: If Harley eats 24 pages of your math book, and 13 pages of your history book, how many pages does Harley eat?  Bonus:  How many more pages of math than history does he eat?

Big kids: You’ve just written an 80-page paper.  If Harley eats 1/4th of it, how many pages does he eat?  Bonus: What if he eats 1/5th of what's left - how many pages do you still have?

A message from Laura:   Bedtime Math is a simple idea: we all know we should read to our kids at night, but what about math?   My husband and I have done fun, mischief-loaded math problems with our kids at night for years.  When at age 2, our third child started hollering for his own math problem, we realized we were onto something:  In a world where so many people say “Ewww, math!”, we had created a household culture where kids don’t just tolerate math, they actually seek it out.   Now we email parents a fun, lively math problem every day to do with their kids – and every week, we’ll be posting a new problem right here on Scholastic Parents!

Wee ones: 9 writing objects.

Little kids: 37 pages.  Bonus: 11 more pages of math (Harley loves math!).

Big kids: 20 pages.  Bonus: Since you now have 60 pages, he eats 12 more, leaving you with 48 pages.
