Introduce young scholars to calendars as they practice the days of the week and four seasons. First graders complete three days-of-the-week sequences, each starting on a different day. They can reference the completed sequence example...

The Magic Pot by Patricia Coombs is the theme of this multidisciplinary lesson plan. Early readers first take part in a read aloud and grand conversation about the story's details. Then, they get to work practicing their skills in...

Investigate the Remainder Theorem in this algebra lesson. Explore the relationship between the remainders of polynomial division and the function. Each of the four problems gets progressively more complicated. This might be a great...

When is a foot not a foot? When you use the length of your own foot to measure distances, of course. To underscore the importance of standardized units of measurement, middle schoolers engage in a series of activities that ask them to...

It's a sign! Scholars analyze sine functions for patterns in their periods. The exploration advances beyond a simple function to the combination of two functions with even and odd coefficients. Their goal is to find a pattern between the...

Point your class in the right direction in plotting points with three activities that give scholars a chance to learn about and practice plotting points on a coordinate plane. They draw figures on the coordinate plane and list out the...

Order up a resource on absolute value and order. The 12th installment of a 21-part module investigates the relationship between absolute value and the order of numbers on a number line. Scholars determine how the actual values and the...

Every moment, the systems in your body are working together to keep you breathing, standing, and thinking. Elementary schoolers explore the human body and its systems with an impressive, 15-page lesson plan that should leave your...

Have scholars show what they know with a 20-page assessment aligned to the California State Standards. The test covers concepts such as large and whole numbers, all four mathematical operations, fractions, decimals, geometric figures,...

Just how big would it really be? Young mathematicians determine if different toys are proportional and if their scale is accurate. They solve problems relating scale along with volume and surface area using manipulatives. The...

These abstract shapes are pointing in different directions and young scholars determine which ones are oriented the same way. For each of five starting shapes they examine a set of four identical figures pointing in various directions,...

Linear equations are all about form. The fifth part in a unit of nine works with the different equivalent forms of linear equations. Class members become familiar with each form by identifying key aspects, graphing, and converting...
