Note: There is now a video tutorial that goes with this activity: Division With Remainders: Just Do It (RIGHT!) Your students are "learning" about division, and if you're using a really, really cruddy curriculum, then they probably all sound like this: "I have 24 blah blah blahs which I'm packing into cases of (choose some divisor of 24.) How many cases will I be able to make. This, my friends, is a lackadaisical and churlish approach to teaching students about solving problems with division.

I know you all love "Task Cards" - so I made these for you, but at the same time, I had to get "snarky." Forgive me..... See all those stoopid questions that show up on Facebook, Instagram, PInterest, Friendster, Tumblr, Twitter, Woof, etc? The ones where they tell you to calculate some easy-peasy problem and then 83% get the wrong answer? Wouldn't that make a great activity for reviewing order of operations, a.k.a. PEMDAS????? So I collected a whole bunch of these, spread them over a few pag

This packet is my way of serving all masters concerning the implications of summer math work: it has a limited number of activities that are not high stress - in fact, it’s five different games, some classic (Picos, Fermis and Bagels, Salute! & PIG!) and others that will be “new to you” (By the Digits, Close to 100), as well as a geometry puzzle featuring the Sphinx puzzle pieces.  Here’s what you get: • Picos, Fermis and Bagels: This is based on the board game “Mastermind,” which challenges

Do you give summer math work to your students? If so, I imagine it's probably a bunch of those cruddy worksheets that you downloaded off the InterWeb, printed out and told your students to complete for next year's teacher by the beginning of school. You know that your students won't use these, and will more than likely wait to the last minute to rush through them and do a crappo job. So what's the alternative? Well, you could send home this pack o' stuff: there's all kinds of fun stuff to keep

This activity was developed for a teacher whose students were having trouble distinguishing between "divide into groups of 5" and "divide into 5 groups...." To help with this, I designed these task cards for her students; working in pairs, they selected a card from a bowl, which could say things like "use 15 pennies: divide them into groups of 3" or "use 15 pennies; divide them into 3 groups." On their "record sheet," the students have a space to draw their solution and then write the equation w

This has been very successful for me both as an assessment and an activity that students can do at centers or at home. There are 10 different story problems, and a board with 10 spots to place them: each one states the operation you would use to solve it. Your students cut out the cards, they read the problems and then tape or glue the correct problem with the operation or operations that would be used to solve it. Most are single step problems, but some require two steps. A fun thing to do in c

Yes, you saw it with rats, turkeys and reindeers; fact it, you're eventually going to buy one of these, so why not snowmen and snowballs? NO JOKES PLEASE! Okay, the concept is simple: take the snowballs numbered from 1 - 6 and arrange them on the three sides so that each side adds up to 9. Rearrange them and they add up to 10. Do it again, and they add up to 11. Then do it one more time and they add up to 12. Record your results and see for the patterns that emerge in the corner numbers. Want

This activity features at least 1 Billion (that's 1,000,000,000) different long division problems. How did I do it? Answer: a very, very small font! All kidding aside, this is an incredibly expandable activity that has an unlimited number of puzzles, with each puzzle having several different solutions. Students start with a blank long division problem, with blanks left where the divisor and dividend should be. Some blanks are not too sophisticated: it may be a single digit divisor into a double
