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...

To commute or not to commute, that is the question. The 26th segment in a 32-segment lesson focuses on the effect of performing one transformation after another one. The pupils develop the procedure in order to multiply two 2 X 2...

Build tables by understanding their structure. Scholars take a closer look at the structure of ratio tables in the 10th segment in a 29-part series. Individuals realize that the tables can be built using an additive or...

The second lesson in a series of 25 shows the class how to use arrows and a number line to add integers. Learners apply their knowledge of the commutative property and absolute value in their explanations. Classmates play the integer...

Develop the rules for adding rational numbers. Pupils continue to work on adding integers. Young mathematicians use their experiences to develop the rules for adding integers with like and unlike signs. They finish the lesson plan by...

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...

Hop your way through a mathematical equation with your first grade class as they learn the idea of moving up and down the number line. Adding and subtracting like little frogs is an engaging and clever way to teach/reinforce this concept.

Test scholars' knowledge of addition facts with a festive instructional activity that makes adding a two-person game. Pairs examine a grid of numbers to locate and color addition facts. Last person to color three squares wins! 

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...

Knowing the addition formulas allows for the calculations of double and half formulas. The fourth installment of 16 has the class use the addition formula to develop the double angle trigonometric formulas. Using the double formula,...

Show budding mathematicans how to find the sine of pi over 12. The third activity in a series of 16 introduces the addition and subtraction formulas for trigonometric functions. Class members derive the formulas using the distance...

Challenge the addition skills of young learners with this open-ended math problem. The task is simple, get from start to finish by connecting a series of three numbers. The trick is that the sum of the numbers must be less than...

Approach addition with young mathematicians in an engaging way through this penguin-inspired activity. In small groups, scholars think about times they have used addition in their real lives (there are some suggestions given), then watch...

Here is a great learning task that focuses on the development of areas in computational fluency including strategies in mental math. Young learners are guided through a list of addition expressions that help them visually understand the...

First graders are exposed to addition of three whole numbers in a math activity centered around Eric Carle's, The Very Hungry Caterpillar. As the teacher reads, young mathematicians use counters and ten-frames to symbolize the number of...

Learning math is so much more fun when it involves playing games. Following the rules of the classic game Memory, young mathematicians flip over two cards at a time as they look for numbers whose sum or difference is equal to the value...

Transition young mathematicians from using repeated addition to multiplication with this fun, hands-on activity. Using manipulatives and the included game board, students work in pairs modeling repeated addition problems before...

Count up or down to find sums. The third instructional activity in a 25-part series uses number lines to build an understanding of the sums of integers. Pupils make the connection between the distance and direction of a sum from the...

Introduces addition of decimals by using unit notation to represent the problem. Pupils use a place value chart to decompose the numbers and then add before connecting to the standard algorithm. 

Your sixth and seventh graders deepen their understanding of a number line and adding integers in this concrete, hands-on activity. Learners play "Warehouse Puzzle" and then discuss their game strategies and the characteristics...

Enrich your study of living things with these cross-curricular math activities. Following along with the story Tillena Lou's Day in the Sun, learners will practice addition and subtraction, learn how to measure volume and length,...

Have fun while building the number sense of young mathematicians with this list of ten-frame learning games. From developing cardinality and counting skills to learning place value and basic addition strategies, ten-frames are excellent...

And they're off! Working in pairs, young mathematicians roll dice to see who can fill in their double ten-frames first. When students finally fill in their arrays, they create addition number sentences that represent their rolls, helping...

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