What does geometry have to do with geometry? The portion of a review series for a math assessment highlights how equation formation is assessed on the test. Pupils use geometric concepts such as perimeter and the sum of the measures of...

Model vector addition graphically. A simple interactive has users add vectors and adjust the lengths and angles of the vectors. The interactive automatically updates the magnitude, angle, and components of the sum.

Stack them together to get a measurement. The short activity has pupils work in pairs to measure the lengths of two blocks and then determine the length of the two blocks together. The groups then determine an equation that represents...

A system is only as good as the sum of its parts! Young scholars explore the components of the different body systems using a hands-on lesson. The lesson helps learners build an understanding that there is a hierarchy of components in...

A five-question interactive provides a horizontal number line where integers are stacked on top of one another to find solutions of addition problems. Mathematicians move numbers to the numbers line, as numbers build higher, the sum of...

A five-question interactive test scholars' knowledge of adding and subtracting decimals. A tool aids in problem-solving with movable parts that reveal addends and sums. Question types include one discussion, fill and in the blank, and...

Try to find the triangles in various polygons. An investigation has learners develop a formula for the sum of the measures of the interior angles of a polygon. They use manipulatives to partition each polygon into triangles, then...

Build a pyramid based on sums. Individuals watch a video of a computer program that creates a pyramid of numbers based upon a starting number. The scholars develop a hypothesis on how the number trick works and share their thoughts on...

An engaging learning game tests scholars' knowledge of how to make a number using addition. Several players race to pick two numbers that add up to a given sum. 

Engage further in Esperanza Rising with a focus on close reading and metaphor. Class members zero in on the tenth chapter, examining characters and big ideas. Pupils discuss the text in small groups and as a whole class, and...

Math class is full of drama—there are so many problems to work out! Pupils work out factoring problems. They use quadratic methods of factoring higher degree polynomials, in addition to factoring the sum and difference of two...

Use the Law of Cosines and the Law of Sines to solve problems using the sums of vectors. Pupils work on several different types of real-world problems that can be modeled using triangles with three known measurements. In the process,...

The ninth part in a 25-part series emphasizes the importance of using properties of operations in evaluating sums and differences of rational numbers. Pupils solve problems and provide justifications for each step.

Pairs with the same sum of integer cards verify the addition and subtraction properties of equality by adding and subtracting like cards to each hand. They also justify the multiplication and division properties of equality using...

Find the cards that get to zero. The activity introduces the class to the idea of adding integers. Pupils use a number line to count up and count down when adding. They play a game to collect cards that will sum to zero.

Apply addition and subtraction of integers to solve problems with rational numbers. Pupils apply the rules for adding and subtracting integers to add and subtract rational numbers. Class members represent the problem with equations and...

Take a spin to determine experimental probability. Small groups spin a spinner and keep track of the sums of the spins and calculate the resulting probabilities. Pupils use simulated frequencies to practice finding other probabilities to...

Even or not, here I come. Groups investigate the parity of products and sums of whole numbers in the 17th lesson in a series of 21. Using dots to represent numbers, they develop a pattern for the products of two even numbers; two odd...

Who knew the sum of a number's digits gives such interesting information? The 18th installment of a 21-part module has scholars investigate division by three and nine. After looking at several examples, they develop divisibility tests...

Take a another look at ellipses. The seventh segment in a series of 23 in a Precalculus module continues to investigate the graph and equation of an ellipse from the previous lesson plan. Scholars investigate the fact that the sum of...

The whole is greater than the sum of its parts. Working in small groups, class members combine their independent readers theater scripts into part of a larger group script. They complete a storyboard to determine the best sequence for...

With endless possibilities, you can create custom flashcards to take to class as easy as 1, 2, 3! Let this flashcard creator do the work for you, just chose the level of difficulty, add or subtract, and the number of place values. Each...

Addition and subtraction are essential skills for all young mathematicians. Explain the step-by-step process with respect to place value using these real-world examples. Focus is on numbers in the tens, hundreds, and thousands, making...

Students find the proper factors for numbers one through fifty using either the divisibility laws or TI-82. They determine the sum of the proper factors for each number. If the sum of the factors is less than the number itself, then this...
