# Homeschool Math Newsletter, Vol. 44, September 2010

Hello all!

Just wanted to share with you two freebies.

1. A lesson on multiplication of integers.

This lesson goes through the positive x negative, negative x positive, and negative x negative. It has basic exercises, a pattern exercise, a riddle, a coordinate grid exercise, and lastly an optional explanation (using distributive property) of why negative times a negative must be positive. The lesson suits grades 5-8, or even Algebra 1 students.

This free sample lesson will (later) be included in Math Mammoth Grade 6-B complete curriculum, and also in a separate book for the Blue Series. Feel free to use it with your students and to share with others.

And... as far as Grade 6-B complete curriculum goes, I'm about to write the last lesson for the integers chapter, and after that I have one more chapter to write (probability & statistics).

2. A science freebie from SuperCharged Science

I've just started using this science curriculum with my fifth grader, now that we're back to school. We both really liked the first video we watched and the experiment we did (which was on density). Aurora does a fantastic job on the video! I hope I will someday be able to be as natural and relaxed as she is when doing my videos.

This sample freebie from them has over 30 complete experiments:

• Over 30 complete experiments...
• Defy gravity as you levitate water
• Crush a soda can using a few drops of water
• Make an indoor corkscrew roller coaster
• Stick your kid inside a real bubble
• Grow crystals overnight
• Create and crack your own geodes
• Build a flying machine that shouldn't be able to fly at all
• ...and much more!

Here's another freebie of theirs that I linked to in my newsletter earlier in July... it has several experiments AND access to the corresponding videos:

3. My favorite music
Lastly... if you didn't see this earlier... my favorite music band's channel on YouTube:
24K Gold Music sampler channel

Lots of hit songs from 50s, 60s, some from 70s... Here are my absolute favorites:
Cara Mia
Tell Him

These ballads just "grab my heart"... but I actually do like the peppy songs too, such as
Burning Love

Here's the channel link again so you can find your favorites:
