Math Links for Week Ending Apr. 21st, 2017

One of the newest type of activities that we are starting to make a lot of is a continuum for student practice and review. It's basically a tricky way to do a worksheet. In this case it is operations with fractions for grade 7 (adding & subtracting and multiplication & division with whole numbers).  The premiss is this: there are seven envelopes. Each envelope has cards with 10 questions. As you move from one envelope to the other the questions become incrementally more difficult. Students have to do the first 5 questions on each card. If they get those correct then the go to the next card, if not they do more on the same one. And to make it a bit more fun we have answer cards for them to check with a UV pen and invisible ink.

Here's a neat little Desmos Activity from @id_rms1 to get kids into the idea of multiplying a fraction by a whole number. Once they are done that then then can use this Mathies virtual manipulative on pouring liquid.

I always like these patterning problems where there are many interpretations of how the pattern grows. Check out the post for more on this. Thanks to @msbjacobs and @AllenMath for this one.

Though this article is a few years old, I don't think we can have enough info about helping students with learning disabilities. In this case, heuristics, math anxiety and more. Thanks to @KMarkPet for this one.

The next time I get a chance to talk about order of operations I'm gonna talk about this. Apparently this professor has written every three digit number as an expression using only one digit and order of operations. For example: 931 = 33 + 33 × 33 + 3 + 3 + 3/3. Watch this @numberphile video from @standupmaths with more on this and even something similar with numbers less than 11,111.
