Worksheets for coordinate grid and volume

Image
Here are some new worksheet generators for my HomeschoolMath.net site, especially meant for grades 6-7:

Worksheets for the coordinate grid. You can make worksheets where students plot points on the coordinate plane, tell the coordinates of points, plot shapes from points, reflect shapes in the x or y-axis, or move them up, down, left, or right (translations).

For example:



Worksheets for the volume and surface area of cubes and rectangular prisms. The options include the usage of fractional edge lengths. You can also ask for surface area when volume is given or vice versa.

For example:

Free practice test bank

Image
Here's a resource for high schoolers (mostly)!

Varsity Tutors has created a massive FREE practice test bank for all kinds of standardized tests, including SAT, SSAT, ISEE, GED, GMAT, HSPT, CLEP, AP, ACT, and ACCUPLACER -- and also generic subjects such as algebra 1, geometry, or calculus. It contains tens of thousands of practice problems.

You can also create a free account so you can save your test results and keep track of progress over time, as well as create your own tests.

Note: this is not for math only but includes English, science, reading, writing, social studies  and so on -- whatever subjects are tested in any particular test.

For gifted students - Elements of Mathematics: Foundations

Image
For gifted/talented students!

I got a note about a limited time offer for theElements of Mathematics: Foundations course by IMACS: you can get 25% off if you order all 5 available courses before the end of January.

You can also purchase the five courses separately. They are:

Operational Systems
This course covers modular arithmetic using secret codes and online games.

The Integers
This course introduces positive and negative integers with an unusual elevator and mysteriously disappearing nuts.

Sets, Subsets and Set Operations
This course introduces the building blocks of set theory, which provides the basic language in which most mathematical texts are written.

Ordered n-Tuples
...interactive features such as taxi driver navigation and the rock-paper-scissors game give context to the properties of Cartesian product sets.

Mappings
Students explore various types of mappings, including permutations, with interactive ball sorters, slide rules and clever animations.

These are online sel…

Great math moment(s) contest

Image
I've run many, many simple contests or giveaways for my Math Mammoth products in the past, and here's another one.

But this one is different -- it is not based on luck.

The prizes are 1. Everything bundle
2. All Inclusive
3. Light Blue series bundle

Each winner can also optionally receive a 24K Gold CD. (Here's a nice collection of videos by 24K Gold for you to check out.)

And... there may be more prizes than this!! : ) I can't really decide on the number of prizes when I haven't seen how many people entered and what kind of entries I get!

The grand theme is:
GREAT MATH MOMENT(S) I want you to WRITE some kind of a success story about math learning in your home/classroom/tutoring etc. -- something that will ENCOURAGE other parents!

It can be one moment or many! It could be for example
a description of a particular math activity a description of your student's study of math over a longer period of time a story of how your student DID something that…

A note about Math Mammoth UPDATES

Now that all 6 grades of the Light Blue series have been revised, past customers can get a free update!


Those of you who have purchased the complete Light Blue series in the past at Kagi store or Educents:

- I have emailed you about the update. You can download the revised version using the info in the email.

Of course, some emails bounced back to me because the email address was outdated so if you suspect that, contact me directly.



Those who have purchased at Currclick:

- simply log in to your account at Currclick and download it from there (in your past purchases section).



Those who purchased at Homeschool Buyers Co-op:

- the co-op has published the update info in your co-op account.




If you purchased the Light Blue series "piecemeal" at Kagi, and not as one single bundle, then you haven't been emailed. You can still get the update but you need to contact me directly.

A 5th grade math story problem about horses

Image
I recently mentioned about changing math problems from closed to open, and gave a few examples.

Just a few days ago my 5th grader was facing a page in Math Mammoth 5 filled with word problems that had to do with conversions between measuring units. So... I asked her to choose and solve 3 problems from that page, and THEN write her own story problem where the solver will need to convert measuring units.

This is what she came up with. I guess I should have guessed the topic. :^)

There are three horses in a paddock, and each weighs a different amount. The first horse weighs 13,760 ounces, the second 1/2 ton, and the last one 1,100 pounds. What is the weight of all the horses together, in pounds? No calculator allowed.
She needed some help, because in her original version, the weights of the horses were not realistic -- but it was good to have a discussion on that, as well.

Try it yourself! Ask your kids to make story problems. You might …

2014 Mathematics Game

Image
2014 Mathematics Game is here!
Read the complete rules at Let's Play Math.

Essentially, you're supposed to use each of the digits 2, 0, 1, and 4 and mathematical operations to form the counting numbers from 1 to 100. It's yearly challenge that is fun for all ages!

I'll get you started with a few easy ones:

1 × (4 − 2) + 0 = 2

20 - 14 = 19

41 + 20 = 61

You can also use square root, factorial, decimals, and some other things.

If you can't quite make it to 100... try do all the couting numbers from 1 to 20 or some other smaller goal. (I was able to do them from 1 to 20 in a fairly short time so that much is definitely possible. We'll have to see if complete solutions exist.

This game is also 'live' at Math Forum where you can submit a complete solution, and possibly get it published.
