### I will derive!

Just a fun little song (parody of "I will survive") for all of us who've taken calculus.

This is a wonderful story by a girl about her experiences with math... have your kids read it! Note how she learns when the teacher allows her to correct her mistakes in a test. I definitely advocate that. In fact, I give my kids HALF of the points they COULD have gotten at first, if they get a test question correct when they revise it. Tests should be LEARNING tools, and help children learn, just like everything else we do in teaching them, and NOT "scary judgment devices". https://blackwomenrockmath.com/blog/f/never-give-up

It's financial literacy month (April), so here's a free nice workbook: A Kid's Guide to Saving: An Interactive Workbook With 14 pages, the guide includes: A calculator that illustrates the magic of compound interest for a child’s understanding Budgeting worksheets to calculate how much to save and set savings goals A quiz to test their learning with a certificate of completion at the end

The two videos below show how you could teach multi-digit multiplication, or the multiplication algorithm, or multiplying in columns to students. Teaching multiplication algorithm Multiplication algorithm with a 2-digit multiplier I approach this in steps. First, to teach students to multiply 4 × 87 or 5 × 928 (one factor is single-digit): 1) Teach students to multiply single-digit numbers by whole tens and hundreds. 2) Teach them the partial products algorithm; 3) Use the above as a stepping stone and teach the usual multiplication algorithm. Then we can go on to the two-digit multiplier: 4) Teach the partial products again. 5) Teach the regular form of the algorithm. Let's look at these steps in more detail. Step 1. This means teaching students to multiply 5 × 80 or 7 × 400 or 3 × 40 or 9 × 900 (mentally!). The shortcut is to multiply without the zero or zeros, then tag the zero or zeros to the result. But, where does it come from? For example, 5 × 80 is the same a

Is it OK if I use it in my class?

I don't see why you couldn't use it. This video is from Youtube and is as public as can be; obviously the maker wants it to get publicity.

Here's the direct link to it. There you can get the "embed" code to put it on your site/blog like I did.
