This interactive applet introduces students to the topic of combinations, a basic concept in probability. Users create combinations of shirts and pants to determine the total number of possible outfits. They may simply explore by placing the clothes on Bobbie, or make a guess and then test it. The number of shirt and pants choices is customizable. An optional voice provides prompts and feedback.

This problem introduces children to algebra by looking for a pattern and generalizing with a rule. Students explore in how many different ways can a stick of 6, 7 or 8 different colored interlocking cubes be broken into two parts. The Teachers' Notes page offers rationale, suggestions for implementation, discussion questions, and an idea for support and extension.

In this 7-minute video Dr. Thomas P. Carpenter discusses the importance of building children's conceptual understanding of fractions by building on their intuitive knowledge of sharing and apportioning objects. Dr. Carpenter provides examples of student responses to challenging problems. A transcript of this recording is available in PDF format.

This problem helps children begin to understand the various properties of common geometric solid shapes. It also promotes naming, discussion and experimentation concerning their features, and requires them to justify their ideas. It asks students to judge the stability of nine configurations made from six common solids. The Teachers' Notes page includes suggestions for implementation, discussion questions, ideas for extension and support, and printable sheets.

In this line plot activity students measure circular buttons to the nearest eighth of an inch and then measure again the same buttons to the nearest quarter inch. Learners create two line plots of their length and draw conclusions about these line plots. Key concepts involved in this task are measuring to a quarter and an eighth of an inch, creating a line plot, and determining which line plot is more accurate.

This sequence of eight lessons from Illuminations provides an opportunity for students to represent patterns in different ways. Students solve problems; make, explain, and defend conjectures; make generalizations; and extend and clarify their knowledge. In Lesson 1 and 2 students recognize, sort, and identify rules for sorting. In Lesson 3 learners identify the core element or unit that is repeated. In Lesson 4 students create patterns and represent them using different forms: pattern blocks, actions, objects, pictures, letters and numbers. In Lesson 5 and 7 students use an Internet-based calculator that is linked with an interactive Hundreds Chart to create, extend, and record numerical patterns in different ways. In Lesson 6 students create patterns with movement and song. The last lesson, Lesson 8 is designed as a summative assessment of students understanding of patterns.
