Hello again! In this month's newsletter we have: |
1. Math Mammoth newsHere are the upcoming sales:
 Here is where you can get Mathy for your own children at Amazon.com. More videos have been added for grade 8. Now chapter 2 videos are complete, and we've started working on videos for chapter 3. This is not a super fast process because I have so many other things I have to take care of, also. Someone else is editing the videos but I still have to plan them, be in them, and final-check them after the editing work. But we will keep going! We're also adding a few videos here and there to other grade levels. At my Youtube channel you can see the videos by date added. Looks like I have 638 videos in total so far (!) — for all kinds of math topics in grades 1-8. Upcoming soon... a new edition for the grade 3 international version (based on the 2024 edition of the U.S. version). Advance notice for those who need it... in the summer, we will have a new edition for Math Mammoth grade 7. Lastly... this is not news, but perhaps worth mentioning. If you work for a tutoring center or school, or are a tutor, we offer a service where we will put your logo or name on all the pages of the Math Mammoth digital products you purchase. If you're interested in this, just reply to this email. |
2. A new activity: add and subtract fractions!We have a new activity for practicing adding and subtracting fractions and mixed numbers. In fact, I venture to say this is the most versatile online practice activity you'll find anywhere, because of the variety of options offered!There can be from 2 to 4 fractions to add/subtract. You can specify the denominators to use (as a list). The practice problems can include proper fractions, improper fractions, and/or mixed numbers. The operation can be addition, subtraction, or a mix of both. The final answer can be required to be in lowest terms or not, and required to be given as a mixed number or not. This allows teachers to generate practice problems for lower grade levels when students have not yet learned how to simplify fractions or how to change them to mixed numbers.  Check it out! |
3. ❤️ For the love of math: FREE math card games ❤️
Pep up your math time with card games from Acing Math — a large collection of math card games.
For example, the game "Multiplication Zone" (p. 30) is a very nice game in that it doesn't just practice multiplication of two numbers, but instead, players need to consider which cards (numbers) they put together to multiply in order to get a product that's in a certain "zone". I have played this with my kids, except we changed it so that an ace is 14 (instead of 11) and the rest of the face cards kept their usual numbers. It's a wonderful book! It has dozens of games, ranging from addition to integers and exponents. Worth checking out! |
4. Division and Its DiscontentsI thoroughly enjoyed this column by Steven Strogatz titled Division and Its Discontents.Division "is the place where many students hit the mathematical wall", he says. Division is mathematically the operation that gives us FRACTIONS... because not everything divides evenly. If you try to divide 9 by 4, you will end up with a fractional part in your final answer.Strogatz takes us through a few short stories, and in the end shows us some astonishing facts concerning decimals, which make it seem that everything is turning topsy-turvy! Enjoyable piece for adults and your middle and high school students alike. 🙂 |
5. "Guess my number" trick
One of those "guess my number" tricks. Can you make an algebraic equation explaining the trick?
