Students add numbers to ten.  In this addition to ten lesson, students play the Ten frame interactive game to learn about addition and facts to number ten.

Imagine a race to complete a puzzle where each person has the same 50 pieces, knows they are missing other pieces, and must figure out how everything fits together. The winner gets fame, listed in books for years to come, and a financial...

Read aloud your choice of books about counting on and counting back (a list is provided, or tell stories of your own). Your learners will write horizontal equations to portray what happens in the story. They build a paper chain and...

Learners participate in an adding game. In this adding numbers lesson, students calculate the sum of the dice and remove a number from their activity sheet.  Learners who first removes the numbers is the winner.

Students view objects sorted by one characteristic and name that characteristic.  In this sorting rule lesson, students explore to find a new characteristic and write a description of that rule.  In early grades the rule might...

Students identify the different properties of quadrilaterals. In this geometry-lesson, students define parallel sides and diagonals of polygons as they compare to a quadrilateral. They identify the methods to find the angles in a...

Students use number lines to compare differences. In this math lesson, students use a number line to solve problems. Students predict differences and answer puzzles using subtraction.

Students determine differences using a number line. In this math lesson, students use the number line to solve subtraction problems. Students solve puzzles using subtraction.

Students describe shapes to their classmates using specific properties and practice making triangles on geoboards. In this geoboards lesson plan, students use string on the geoboards.

Students analyze and solve word problems. In this algebra lesson, students explore their reasoning skills as they analyze a problems and come up with the correct steps to solve it. They create a plan and execute it correctly.

Students rewrite equations using algebraic symbols. In this algebra lesson, students graph linear equations using the slope and y intercept. They make predictions about their graphs and analyze the results.

Students compare two cell phone providers and relate those concepts to motion. For this algebra lesson, students identify the unknown in a problem using variables. They calculate the velocity, motion and displacement of different objects.

Learners identify different parts and properties of circles. In this geometry lesson, students identify the radius, diameter, semicircle and inscribed angle of a circle. They identify the tangent lines to a circle.

Students calculate the solution using half angles formulas. In this calculus lesson, students identify the different properties of a triangle using trigonometric properties. They identify the mean, altitude and angles of a triangle.

Students solve problems involving triangles. In this geometry lesson, students apply properties of triangles to find the missing angles and sides. They identify angles of parallel lines cut by a transversal.

High schoolers identify different polygons. In this geometry lesson, students name polygons using the number of sides. They calculate distance and slopes using the correct formula.
