She is the first woman to win a Fields Medal!

Fun & artistic fractions tool

Here's an online fractions activity that is somewhat artistic and that some of you might find fun.

Unitize fractions on a grid

Conceptua Fractions is offering this tool for free during this summer. Here's a screenshot:

Unitize fractions tool

First, you drag a red rectangle or a triangle that is going to be your UNIT. It corresponds to 1.

Then, you make rectangles and triangles of the other colors. Your task is then to figure out their area compared to the UNIT you established in the beginning, and type it in as a fraction or a mixed number.

For example, in the picture below, my UNIT is actually 4 squares. The blue rectangle is 6 squares, so its area, compare to the unit, is 6/4 = 3/2.

Worksheets for inequalities

More new worksheet generators... This one is for linear inequalities in one variable.

The worksheets are customizable in many different ways. You can ask the student to plot simple inequalities, such as x < -6 or write an inequality from a graph. One problem type asks you to solve the given simple inequality in the given set, such as solve x + 1 > -2 in the set {-9, 3,5,8, -2, 10}.

Then you can choose from six different types of linear inequalities to solve (such as one-step inequalities, two-step inequalities, or inequalities with variable on both sides).

You can also restrict the inequalities to the ones where you don't need to multiply/divide by a negative number (which would reverse the sign of the inequality).

These worksheets are meant for pre-algebra and algebra 1 (or grades 7-9).

Math Mammoth photo contest winning entries

Here are the winning entries for the photo contest I ran recently. I asked each participant to provide a photo showing a child/student(s) doing math work from a Math Mammoth book or materials. Click to see a larger version. Enjoy!

1. I felt this picture was just so cute and also the composition is great.

"Isabelle is proudly showing her mom her correctly formed 3's. She wrote them backwards at first. She is working out of her big sister's 1st grade workbook from Math Mammoth's Light Blue Series."

The second place was a tie — I just couldn't decide.

2. A. First, school work upside down - quite creative!

"Here is a pic of my son doing his Light Blue 4 work. I have the download version and printed and bound it in parts because he likes to move around a lot while he works."

2. B. From Amy (no description). I feel this also is a creative shot and shows students with a very happy disposition.

3. "My daughter loves to do her Math Mammoth outside."

The rest of the winners are not in any particular order.

I like this shot a lot. The children are hard at work, and it shows how some exercises in Math Mammoth can be done with manipulatives.

"We are a school based in Lagos, Nigeria."

Interesting angle. Must be enjoyable to work on your math in the shade on a hot day.

"We are excited about the flexibility of Math Mammoth - just print off the pages you need and take it on the go. If you make a lot of mistakes, print it again! It is also nice the way it lends itself to manipulatives. You can easily see how to translate a lesson into a hands-on experience."

A nice photo showing a brother and a sister working together.

"Snuggling up with our favorite sibling and our favorite math curriculum!"

A winning combination here! Mathy in the middle is a plus. :)

"Joseph (8) working on 2B and Faith (6) working on 1B - along with their pal, Maximus (they have renamed the wooly mammoth). This is Joseph's second year and Faith's first using this program. Thank you!"

This is a wonderful concept: "Math is better when shared with friends!"

Click to see a larger version. These animals seem to really love the girl. A peaceful picture.

"Our daughter Julia-Grace, her duck Faith, our sheep in the background on a few and our dog, Mocha."

This is just a lovely picture and a lovely guinea pig. :)

"Here is a photo of our daughter, Megan, and her guinea pig, Cocoa, doing the 6th grade Math Mammoth book together. Math is more fun with a friend!! Love your math curriculum! We have been using it as an after-school and summer program for our daughter for about 2 years now. It has made a huge difference in her math abilities and self-confidence. Thank you so much for all you do!!"

A really 'cozy' picture, makes you feel warm and calm inside.

"Homeschoolers may not get snow days, but we get our fair share of Math Mammoth by the fire days!"

She seems so happy. Did you know Math Mammoth books can be filled in on the computer, as well?

"My daughter Paige is doing Math Mammoth on the computer from the downloaded light blue 5th grade material. We are inserting text and equations in the pdf's using OneNote."
