This interactive applet helps students develop fluency and flexibility with numbers. At each of 6 difficulty levels the user is presented with 8 target numbers and a partial set of keys on a basic calculator (does not follow order of operations). The goal is to use the given keys to make as many of the target numbers as possible within the 3-minute time limit. Some levels include memory keys.

In this Cyberchase interactive simulation students help the Cybersquad gather bugs to create a bar graph by sorting the bugs into the correct columns by color. Once three graphs have been created they are prompted to answer a question comparing the graphs, all of which have different scales. The simulation includes instructions and hints.

In this series of three lesson plans, students create bar graphs, double bar graphs, and determine appropriate intervals for scale. Each lesson incorporates teacher modeling, student practice (students have an opportunity to label and create the scale for their own graphs), assessment (including rubrics), and reteaching or extension options.

In this lesson plan students watch a video clip of Bianca as she uses Venn diagrams to try to satisfy three people's preferences in pizza toppings. Students practice using Venn diagrams to represent the pizza topping preferences. Learners are then introduced to prime numbers, prime factorization, and the use of Venn diagrams to determine least common multiple and greatest common factor. Support materials are included: Handout: Gleamers and Glow Power, Assessment: Levels A and B and answer keys are provided.

In this number sorting activity students must use a Carroll Diagram to determine which two categories each number fits into. This activity can be completed in pairs or groups on printable versions or it can be completed as a whole class using the interactive white board (IWB). Included with this resource are printable versions of the Carroll Diagrams, guiding questions, extension and support suggestions, and a link to more challenging "More Carroll Diagrams".

This interactive Java applet helps students understand place value and regrouping. Base 10 is the default, but users may choose to work in base 2 or 5. A user places (or removes) chips of three colors in three columns to represent numbers of up to three digits. When the number of chips in any column equals the base number, the user can exchange them for a chip in the next column. Similarly a chip of a higher value can be exchanged for the base number of chips of the lower value. The applet can be used to model addition and subtraction with regrouping.
