FREE Number Sense Technology Tools

I love combining great math with technology. If that sounds good to you, too, you’ll want to check out these free number sense technology tools from DreamBox.

You’ll find this interactive rekenrek in the Kindergarten Number Sense and Equivalence section. Rekenreks help students develop strong benchmarks of five and ten, a key component of their developing number sense. Use the Show Card and Hide Card buttons to flash cards for the students, who tell you the number they saw represented. Don’t forget to ask how they saw the number.

This matching game for combinations of 10 (and 8 and 9) is found in the Kindergarten Addition and Subtraction section. Because of the role ten plays in our number system, fluency with the combinations of ten is essential for number sense.

In this 2nd grade game, students try to prove equivalencies for 20. You’ll find it in the Second Grade Number Sense and Equivalence section. Many students think that the equal sign means “the answer is coming.” Activities like this emphasize the true meaning of the equal sign.

Students can show their strategies for adding on an open number line in the tool found in the Third Grade Addition and Subtraction section. LOVE this one!! There’s also a Second Grade version. Number lines are fabulous tools for students to use to document their strategies for addition and subtraction.

Speaking of number lines, this activity, found in the Third Grade Number Sense and Equivalence section, has students place fractions on a number line. Number lines help students recognize that a fraction is a number with a specific place on the number line.

        1. 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!

  1. 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.

  2. 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

    1. It’s not really something you download. It’s a website that you can access by clicking on the links in the post.

  3. I live in South Africa and would like to know whether it is possible to use these free Teacher Tools on my Interactive White Board. It seems like I cannot get access to the tools.

    1. Gosh, I don’t have an answer for this! You might have to contact the help function for Dreambox.

      1. Hello..just got a promethean board in my first grade classroom and I’m in need of activities. Are these no longer free or am I doing something wrong..lol? I would love any advice and can I too get the number poster? Thanks so much!!

  4. Hi Donna,

    Looking for your email address. I’ve been reading your blog on twitter and here for about a year and remember you saying you’re in the Houston area and have a meet up group to discuss Math education. I would love to join the group for a meeting or as many meetings as you all find me a useful participant.
