Positive and negative numbers are everywhere in the world around us. Whether it's charged particles in atoms, a hot air balloon rising and falling in the sky, or a series of bills and checks being delivered in the mail, this...

Elementary schoolers review their knowledge of addition and subtraction through studying fact families. They use cubes to help them add or subtract. Young scholars answer the teachers question with addition and subtraction fact answers.

Add an outstanding resource to your repertoire. The first installment of a 36-part module looks at the relationship between addition and subtraction through an activity using tape diagrams. Pupils develop the identities w – x + x =...

Developing fluency with basic addition and subtraction is fundamental to the success of all young mathematicians. This four-day lesson series begins with learners using ten-frames and hundreds charts to recognize patterns when adding and...

See how division and subtraction go hand-in-hand. The fourth installment of a 36-part module has scholars investigate the relationship between subtraction and division. They learn using tape diagrams to see that they can use repeated...

Explore the concept of the equals symbol. In this mathematical symbols lesson, learners discover the meaning of the equals sign (symbol). They also construct addition and subtraction sentences to understand the concept of equal parts.

Second graders access prior knowledge of addition and subtraction using two-digit numbers and calculate easily with them. In this three-digit addition lesson, 2nd graders learn to add and subtract three-digit numbers with and without...

Now you see them, now you don't! This fun peek-a-boo activity engages young mathematicians in developing their ability to compose and decompose numbers. After being presented with a series of counters, children close their eyes while the...

Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves...

A great aspect of teaching math is that children have the freedom to solve problems using a variety of different strategies. The focus of this lesson is for young mathematicians to become aware of many ways of answering addition...

Entertaining as well as educational, this math activity about decomposing numbers is bound to capture the engagement of young learners. Given a cup and five two-color counters, young mathematicians simply shake and spill the cup,...

For this math worksheet, students add thirty-six pairs of signed numbers. The first twenty-eight problems involve integers. Six problems involve signed fractions. Students compute with signed decimal values for the final six problems....

Just because one integer is larger than another doesn't mean it will make sense right away. Go beyond note taking and show learners, through the use of algebra tiles and a Four-Pan Algebra Balance, how the numbers relate to one...

Your learners will enjoy playing a game as a motivator to learning and remembering the adding and subtracting of fractions.

In this decimal addition and subtraction worksheet, young scholars use a computer program for initial instruction, then complete 22 problems with decimals.

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...

Scholars learn how using algebra tiles to add and subtract polynomials can model how to combine polynomials. They use their newfound knowledge to complete a worksheet of problems.

Third graders determine the outcome of each of the following situations and justify their findings: even number + even number = ?, even number + odd number = ?, odd number + odd number = ?, and odd number + even number = ?.

Welcome to Fraction City! This is an incredibly interactive and fun way to teach properties of fractions, and reaches multiple learning styles. Scholars create "blocks" by folding strips of paper in various increments (thirds, fourths,...

Second graders practice their problem solving skills. In this addition and subtraction skills instructional activity, 2nd graders solve word problems that require them to find differences and sums. This instructional activity features...

A short video introduces place value in addition and subtraction. As a class, your students identify all even numbers up to one hundred and explain the pattern. They use addition strategies to fill in the missing numbers on the number grid.

Your class can explore standard and expanded notation, as well as computation with regrouping. They listen to a make-believe story about cavemen and the origin of numerals and place value. Then apply what they learned about renaming and...

Rules are meant to be broken ... but not integer multiplication and division rules. Learners use chips to model integer multiplication and division. The results of the activity help them develop integer rules for these operations.

Getting a meal, side dish, drink, and dessert can be delicious—but it can be expensive too! Practice addition and subtraction with money in a lesson plan that focuses on a sample menu, complete with task cards and word problems.
