Check out this interactive rekenrek. Use the Show Card and Hide Card buttons to flash cards for the students, who tell you the number they saw represented.

Here’s a matching game for combinations of 10.

In this 2nd grade game, students try to prove equivalencies for 20.

Students can show their strategies for adding on an open number line. LOVE this one!!

Speaking of number lines, this activity has students place fractions on a number line.

Fabulous, don’t you think? Especially when it’s FREE. 🙂

There are two parts to the DreamBox website–a paid component for students to use and the free teacher tools, which is what this post is about. Follow the links in the blog post, and they’ll take you right to the teacher tools!

I don’t know if it’s me or the program, but I was trying out the 5th grade “Multiplying fractions” portion, and it wanted me to build and shade 1/6 of the portion. But it didn’t give a 1/6 option, then after I got it to give it to me (by missing too many times that it helped me) it wanted me to shade 1/10 of 1/6th of the unit square. But the only fractions I could multiply against 1/6th was 1/2, 1/3, 1/5, 1/7, and 1/11th. Not sure how to do it. So I’m not sure if there is something wrong with the program. But it doesn’t seem like it will work for this program. So I highly recommend using each program before you let your students use it.

Hi:

I think to figure this out you need to be thinking about the associative property of multiplication. http://www.amathsdictionaryforkids.com/dictionary.html

It works the same way with fractions as it does with whole numbers. e.g. 10 X 6 = 2 x 5 x 6 = 60

So, think about what fractions you need to multiply together to get a certain fraction.

1) To figure out 1/6 of the total you first need to find 1/2 and then 1/3 of 1/2. (1/2 x 1/3 = 1/6) Then your square will be divided into 1/6s.

2) After that to find 1/10 x 1/6 you need to think 1/2 x 1/5 = 1/10 so 1/2 x 1/5 x 1/6 = 1/10 x 1/6 = 1/60

I love the activities and would love to use with my kindergarten students. Is this something you have to buy or how can I access it?
