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.
Fabulous, don’t you think? Especially when it’s FREE. Be sure to spend some time exploring all of the Dreambox Teacher Tools! 😀
