| Equation Editor (use for assn 12) |
These are the same videos as you
will find in the link to assn 12. Using Equation Editor part 1; part 2 If you find that you do not have Equation Editor in your copy of Word (it did come free with Word, but it may not have been installed) an easy fix is to download and install the 30 day free trial version of MathType. After 30 days, it turns into Math Type lite which is very similar to Equation Editor.. |
Goal: The goals this week are for you to
Basic facts: what are they, why should we teach them, how can we teach them.
I want you to start out by reading a couple of papers that have been very influential for the way I think about math facts. Right now, I'm just going to have you read a couple of things, and then answer a few questions about them.
Readings:
Read a lot of the FAQ Basic Facts: Questions, Answers & Comments that Ed Rathmell has written. We will be looking at specific addition and subtraction fact strategies in the next few lessons, so if you are looking for something to skip, you can skip some of that. Make sure you read the sections
- "What does it mean to teach basic facts?
- What do we know about teaching basic facts?
- How can we teach thinking strategies?
- When is basic fact drill appropriate?
- How should you assess children on the basic facts?
