In this interactive, use logic to solve three riddles involving a jumping wallaby competition. Then, using knowledge of inequalities and rational numbers, place the wallabies on the correct range from -5 to 5 on the number line. Numbers...

Given a problem situation, the student will compare and order integers, percents, positive and negative fractions and decimals with or without a calculator.

Given a problem situation in verbal form, students will select and use an operation involving rational numbers in order to solve the problem.

In this interactive, use logic to solve riddles involving a wallaby jumping contest. Add two consecutive jumps and place them on a number line, finding equivalent fractions and common denominators to do so. Backward jumps represent...

In this interactive, use logic to solve riddles involving a wallaby jumping contest. Then, place each contestant's jump-a fraction, mixed number, or decimal between -5 and +5-at the correct point on the number line. Backward jumps are...

Given real-life problems, the student will select an appropriate method and solve problems involving proportional relationships.

Students add and subtract plays on a football field to practice working with negative and positive integers on the number line.

Discusses what numbers are and how our understanding of them has evolved over thousands of years, from simple counting to negative numbers and irrational numbers, for example. Includes a set of practice questions where students identify...

A comprehensive guide for learning all about real numbers and their important properties with solved examples and practice questions.

In this interactive, students add and subtract plays on a football field to practice working with negative and positive integers on the number line. Each set of randomized drives consists of seven to nine plays and ends with a touchdown....

The goal of this task is to examine sums and products of rational and irrational numbers. One important property of rational numbers is that their decimals always terminate or repeat: using a slightly different formulation, a rational...

In this interactive, use logic to solve three riddles involving a jumping frog competition. Then, using knowledge of inequalities and rational numbers, place the frogs in the correct range from 0 to 5 on a number line. The fractions,...
