Do big bodies make big brains? Let your learners decide whether there is an association between body weight and brain weight by putting the data from different animals into a scatterplot. They can remove any outliers and then make a line...

With so much talent in the classroom, do your musicians and athletes have related interests? This problem has your learners taking data from their classmates to decide whether there is an association between the two activities. The...

In this second of three activities, energy engineers plan and create a hydropower dam as they learn how hydroelectric power plants generate electricity. A hydropower puzzle is also included, which can be worked on by teams that finish...

Math games, especially in the primary grades, provide great opportunities for developing the number sense of young mathematicians. Working in pairs with a deck of single-digit cards, students take turns drawing two cards and reading the...

Young mathematicians spin their way to a deeper number sense with this fun, collaborative activity. Using two spinners, one with the numbers 0-9 and the other with the decades 00-90, pairs of students take turns building and comparing...

Fill those extra ten minutes of math time with this fun counting activity. Given a short sequence of numbers, young mathematicians stand in a circle and count one-by-one until the last number is reached, at which point the whole group...

Young mathematicians concentrate on learning to fluently count. Following the rules of the classic game Memory, children take turns flipping over cards in order to find pairs of numbers that cross a decade (e.g. 29 and 30). For younger...

Have a fun time teaching children to read analog clocks with this whole-group math activity. Using large sets of the numerals 1-12 and 0, 5, 10...55, the teacher creates a large clock on either the carpet or the white board, explaining...

Take stroll around the classroom while teaching young mathematicians to count fluently with this whole-group math activity. The teacher starts things off by walking around the room while counting up from the number one and continues...

Introduce young mathematicians to concepts of financial literacy with this open-ended word problem. With seven dollars to spend during field day and given a list of available items and their prices, children must determine how they want...

Raise children's awareness about the importance of conservation with this hands-on science lesson plan. Start by breaking the class into groups and having them collect trash from around the school or local park. Students then use the...

Your young landscapers do concentration calculations in this problem dealing with mixing fertilizer. Learners use and analyze rational expressions within this context.

Your young physicists analyze the forms of four equivalent exponential expressions representing an amount of a radioactive material in a substance. They show how each expression is equivalent to the others and what aspects of the decay...

Learners rewrite a general quadratic function by completing the square to see a new form of the function that more easily identifies the x-coordinate of the vertex and the two roots of the function.

Comparing the movement of graphs geometrically when small changes are made to the parent function motivates this collaborative discussion on the transformations of functions to their various forms. Vertical and horizontal shifts due to...

Cover one-point perspective through observation and practice. Class members examine several works of art that use one-point perspective, look at magazine images to find the vanishing points and horizon lines, and draw their own city...

Play with dimensions and practice making a two-dimensional scene look three-dimensional. Class members view pieces of art and then make their own scenes by layering different materials and drawing in details. Check out all the tabs for...

Your learners analyze population data to discern if it best fits a linear scenario. The idea of change by equal differences over equal intervals is enforced in this real-life task. 

Modeling population growth gives learners an opportunity to experiment with real data. Comparing the growth rates in this real-life task strengthens learners' understanding that exponential functions change by equal factors over equal...

Your young bankers compare earning interest accumulated yearly and monthly to decide which method most increases their balance. Using an exponential function to model the bank balance affords the learners more practice connecting...

Your young fishermen learn about exponential function growth by interpreting the pieces of the given equation within the context of numbers of fish in a lake.

Your learners will explore linear functions by analyzing a graph of the linear equations.Then learners analyze through calculating f(x+P) and g(x+p)

Your algebra learners analyze and interpret the general form and the graph of two functions. The increase of the function due to the multiplicative factor is emphasized.

Your algebra learners discover that exponential functions, with a base larger than one, outgrow linear functions when the inputs increase sufficiently. Their analysis includes using a graphing calculator to produce tables.
