Explore fractions using different manipulatives and illustrations. Your class can create a variety of models of fractions and mixed numbers with drawings and manipulatives. They then work to compare fractions, mixed numbers, and whole...

Students demonstrate whole numbers through one thousand using base ten blocks. They model and describe given numbers using ten blocks.

Put on your math caps and explore place value and ways to represent numbers. Learners read, write, and represent whole numbers. They interact with numbers as they read and explore a teacher-created story, play games, and practice their...

Even though pennies seem to be relatively thin, stack enough of them into a single stack, and you could have quite a high stack. Enough so, that the final result can be a surprise to you as well as your class. This activity centers...

Looking at numerous examples of triangles, each with different properties, geometers develop their understanding of congruency. They use the notation of a counter-example to disprove certain conjectures and prove geometric theorems and...

Why are right triangles so special? Pupils begin their study of right triangles by examining similar right triangles. Verifying through proofs, scholars recognize the three similar right triangles formed by drawing the altitude. Once...

Exponential functions and their growth rates are explored concretely using tables in a collaborative task. Then the successive quotient is explored algebraically.

A short, multiple choice assessment that determines your 3rd graders' ability to correctly compare fractions with like denominators. This quiz asks learners to compare two fractions using words, the greater than/less than symbols, and...

In this college level Pre-Calculus worksheet, students determine if a given relation is a function, graph functions and observe their behavior, and determine if a function is even, odd, both, or neither.  The four page...

Students define Pascal's triangle and special notations used to represent nth elements. In this geometry lesson plan, students solve problems using permutations and combinations. They compare the formula for permutation to that of...

Fractions can be tricky. Why not have kids think of fractions like they think of eighth, quarter, and half notes? In teams, the class creates four-measure patterns with their percussion instruments. They need to explain their rhythm...

Build on the understanding of finding angles using trigonometric ratios. Pupils develop the definitions of inverse trigonometric functions by restricting their domains in the 13th lesson of a 16-part series. They use inverse functional...

Prove that an equation in slope-intercept form names only one line. At the beginning, the teacher leads the class through a proof that there is only one line passing through a given point with a given slope using contradiction. The 19th...

Working independently or in teams, your class practices connecting graphs, formulas and words. This lesson includes a guided discussion about distance vs. time graphs and looking at how velocity changes over time.  

How do you know if a number is divisible? Instructors first prove the divisibility rules for three and four and then class members use this modeling to prove given divisibility rules for eight and nine either individually or in...

Paper or plastic? Explore the environmental effects of using plastic bags through mathematics. Learners manipulate worldwide data on plastic bag consumption to draw conclusions.

Aspiring astronomers solve problems involving mixed units of the same attribute, including time, money, length, and area. They convert large numbers into scientific notation, then compute and compare ratios to explain why drawing...

Count and compare numbers and fractions using "greater than" and "less than." Learners count on by 2s and 10s and represent the end number with base ten blocks, counters, and cups. They use circle stickers to illustrate fractions and...

In this fractions/interval notation worksheet, students write expressions as single fractions, complete problems with nonzero real numbers with unknown values and write sets in interval notation.

Learners explore the extreme between the distance to the moon in comparison to the size of a particle of moon dust and solve problems related to the Apollo space missions.

Explore how to make a number line and how to mark the numbers along the number line using fraction and decimal notation. Your scholars will compare and order fractions and decimals and find their appropriate position on the number line.

Seventh graders solve inequalities using addition and subtraction. They write number sentences based on word problems.

Rotate this resource into your lesson plans. Scholars rotate polygons in the coordinate plane by multiples of 90 degrees. They then compare the original and new figures to develop conjectures about coordinate points after rotations.

First graders complete a number of activities that increase their number sense and use of simple operations. They use dice and worksheets to make two-digit numbers and to record them, they count by tens and ones, and order numbers using...
