Written to assess high schoolers' knowledge of interpreting expressions that represent a quantity in terms of its context, this machine-scored task also allows for a good discussion about units guiding the problem solving and solution.

You have the answer and a variable, but something is missing! The class fills in the missing addend in 23 practice problems that all add up to 10. This is a great way to build number sense, pattern recognition, and automaticity.

Derive tangent lines through derivatives. Scholars use an app to graph functions and investigate derivatives and tangent lines. The interactive automatically graphs a tangent line at a specified point and can also produce tables of values.

A five-question interactive boosts proficiency in working with binary numbers. Multiple-choice, short answer, and discussion questions challenge mathematicians to write numbers 25 through 31in exponential and binary form. An adjustable...

Elementary schoolers use a function machine in order to help them look at the relationship between input and output, and to look at the rule for the change. The machine is actually a cardboard box, and it serves quite well for the...

Lead the class in a review of the basic concepts and procedures involved in measuring length, weight, and volume. After whole group instruction, small groups and individuals practice measuring by completing a variety of fun activities...

Fifth graders define vocabulary terms, identify the characteristics of a pillbug, and create a dichotomous key. Then they examine the pillbugs and make observations and record these observations. Finally, 5th graders observe specific...

Students are presented with the problems of percentages and focus upon numbers in contrast to 100. They calculate problems with money and are engaged with the use of games as a teaching tool. Students also interpret data as presented in...

Learners discover the property of density while participating in a lab exercise. In this scientific measuring instructional activity, pupils utilize a scale to measure the density of different metal materials. They document their work...

Help young mathematicians read and interpret numbers from 1 to 10 and sequence them correctly with this card game. Using a deck of cards and two to three classmates, have one player hand out ten cards to each gamer and then put the extra...

A cross-curricular resource that takes the electoral votes and allows your learners to organize and analyze the data. Young voters can determine which states are more influential and interpret the dotplot provided for more data....

Here is a coin problem where the algebra learner determines the pair of linear equations needed to solve the system. Whether the equations are taken from a table, or your scholars recognize the format of a coin problem, it is an...

Learners construct and use inverse functions to model a real-world context. They use the inverse function to interpolate a data point.

If a linear function and a quadratic function enter a boxing match, which one would win? Learners first review how to find key features of linear and quadratic functions. Next, they compare key features of pairs of functions.

Learn how to represent functions in multiple ways. Learners analyze functions as equations, graphs, and verbal descriptions. The analysis includes intercepts, behavior, domain, and range. The module of seven lessons makes up the third...

A well-designed, comprehensive, and attractive slide show supports direct instruction on how sonar and echolocation work. Contained within the slides are links to interactive websites and instructions for using apps on a mobile device to...
