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.
Check out this interactive rekenrek. 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.
Here’s a matching game for combinations of 10. 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. 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. LOVE this one!! Number lines are fabulous tools for students to use to document their strategies for addition and subtraction.
Speaking of number lines, this activity 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. 🙂
