10- Compare Numbers: What's the difference? (Visualized on a scale):

Niveethan in grade 3 holds the record of 106. Great job!

11- Equalize!!! (Visualized on a scale)

By adding and subtracting ones and tens you can equalize the two sides on the scale. This resembles adding and subtracting base 10 blocks. Write down your answer before deciding what to add or subtract. Check to see if you are right.

Instructions:

  • The collection of programs above generate countless different equations with a missing number. The questions are randomly generated. In the 5 minutes that you have, solve as many equations as you can. Each time you answer a question correctly, you earn a point. You can peek at the answer but this would cost you a point that you get back when you click the right answer. The Reveal feature was added mainly for practice purposes, when you need to check your answers and strategies before making a selection. The annotation feature was added to help students and teachers model problem solving strategies right on the page. Test your skills and practise to improve your personal high score! The first answer is given (arrow points to it). The first 2 programs help students visualize equations and inequalities using a scale. One is called "What's the Difference?" where you have to find the difference between the two sides of the scale. A set of activities deal with integers. These are great for older students. All programs can be used as either practice or test and they generate randomized questions and answers that are numbered in the millions!!! When used properly, they are proven to improve number sense and computational skills in students.

Suggested Lessons or Activities:

  • This resource is great for enhancing students' number sense and numeration skills. Discuss strategies commonly used to solve simple algebra problems. This resource can also be used to improve mental math strategies and speed of basic computations. Initial trials show great promise with all students deepening their understanding of operations and sharpening their skills everyday. Play one game a day (only 5 minutes)!

Special Features:

  • full screen
  • stopwatch (5 min)
  • countless different equations to solve
  • annotation to show strategies
  • collection of different resources focusing on different skills
  • works very well with Interactive Whiteboards and Flash enabled tablets
