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...

Groups explore sets of 10 items in two varieties (i.e. 3 white buttons and 7 black ones, or 5 bears and 5 bunnies). They brainstorm about their objects, write math sentences to represent what they have, and report their discoveries...

Students explore adding 2-digit numbers. For this math lesson, students identify 2-digit numbers and use base ten blocks to practice adding. Students use addition to break a code.

Practice basic operations for young mathematicians in fun ways! Using two decks of cards (Ace through 10 plus the joker), learners play "memory" by matching numbers that can be added to make 10 and writing number sentences. In another...

Count up or down to find sums. The third lesson 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 first addend, then...

Practice basic addition facts and measuring skills. In this addition and measurement lesson plan, students are provided with drywall tape and work in groups of four at a long table. Partners take turns generating addends and marking the...

Second graders use black and red construction paper to symbolize different one digit numbers that add up to 10. In this sums to 10 lesson plan, 2nd graders discover different combinations and patterns that can lead them to the number 10.

Help your young mathematicians completely master 10 by practicing one-to-one correspondence, number recognition, and recording numbers displayed. They make 10 with groups of two-different colored cubes and color in 10-frames to show how...

Fourth graders develop strategies for identifying geometric and number patterns. In this mathematical patterns lesson, 4th graders use pattern blocks to make repeating patterns with numbers and shapes. Students then explore number...

Students read a story and write math problems.  In this reading and math comprehension activity, students preview and read the book "One is a Snail, Ten is a Crab".  Students predict ways to get a sum of 11, write math...

Students are able to use the Fishing for Numbers game in Reader Rabbit's Math. They are able to select two addends that sum to the given number between 1 and 12. Students work in pairs and go to the computer stations and complete at...

For this adding more than two numbers worksheet, students, working with a partner, calculate the answers to eleven addition equations.

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 = ?.

Young mathematicians explore two-digit subtraction. They will investigate multiple ways to subtract numbers involving regrouping. Resources are provided.

Students solve single variable equations. For this missing addend lesson, students solve problems with missing addends. Students create a function box to help study numerical reasoning.

Second graders have an opportunity to work in pairs as they search for the missing addend to complete a mathematical sentence. They identify and demonstrate the ability to change the order of the addends and still produce the same sum....

View a PBS video entitled Horatio's Drive and explore Horatio's Ratios. Collaborative learners form groups to use Mapquest to determine distances covered. They generate the mathematical averages, ratios, and rates in order to calculate...

In this elementary math worksheet, 2nd graders complete 33 horizontal addition problems. They work with one digit addends in each problem.

Students explore solving addition and subtraction problems. They solve real life problems. Students participate in a simulation activity to find the missing addend. They demonstrate adding and subtracting whole numbers.

Young mathematicians research and discuss real world math word problems and ways in which they apply math concepts in their everyday lives. They create a storyboard of a math word problem from which they create a slide for a multi-media...

First graders count bears to predict missing addends. They analyze the missing addend sentence: 7 + ? = 10 and count up from 7 to 10 and check to see if there are 3 bears in the box.

Create a class of mathematics master. They practice addition to ten until they have mastered the skill. They use their hands to add numbers and eventually find the missing addend to make a sum of 10. They also subtract a single digit...

Students notice a number pattern in the book The Rabbit Problem by Emily Gravett. In this number pattern lesson, students represent and describe numbers appropriate to their grade level.

Student study addition properties. In this addition properties lesson, students use multiple methods to solve various types of problems. Students illustrate and describe in various ways the Commutative Property of Addition. Students...
