Mixture problems are a classic in first-year algebra. Unfortunately, many learners approach them in a formulaic fashion and don't truly understand the meaning of the algebraic expressions they are using. Here, the questions are not the...

Determining relationships is all part of algebra and functions. Your mathematicians will decide the type of relationship between airports and population and translate what the slope and y-intercept represent. The problem is multiple...

Using a 100s chart or a number line with a pointer, work with your class to count up to 100 by ones and tens. As a part of daily instruction, prompt your kindergartners to chant count from 1 to 30. Move on to 1 to 50, and then from 1 to...

Sixth graders design and draw a model playground to scale. They configure the layout to include a sandbox, slide, baseball field and other equipment. Their design includes adaptations for students with disabilities. Their designs are...

Your learners analyze various real-life contexts to decide if each is a linear or exponential model. This could be used as an assessment of learners' skills of discerning between a linear and an exponential model.

Help mathematicians see that a formula found in a physics book has an algebraic structure. Though the formula given in the resource looks complicated, learners are to break down the expressions and interpret each part separately....

Here is an activity that is intended to highlight a very important issue about precision in reporting and understanding statements in a realistic scientific context. Discuss different ways of reporting the half life of Carbon 14...

Students create a scale model to a castle using the dimensions they were given. They calculate the surface areas and volumes of each section of their castle.

The Applet illustrates how to use the old-fashioned tables of normal probabilities and areas under the normal distribution cureve to arrive at corresponding graphs of the areas. A good resource for the topic.
