First graders are the counters in addition problems. In this addition lesson, 1st graders replace the counters to help students visualize problems in addition.

Students practice finding the sums of two-one digit numbers. In this addition lesson plan, students also record facts onto an addition chart.

Students examine the concept of addition by adding two one-digit numbers whose sum is less than ten. They count and add goldfish crackers together, chorally repeating each problem.

First graders recall place value system and double-digit addition, create and manipulate double-digit regrouping, and devise and identify ways to use regrouping.

In this addition and subtraction instructional activity, students review the addition properties and the subtraction rules. Students then complete each number sentence and tell which property or rule was used.

First graders practice subtraction with manipulatives. In this subtraction lesson, 1st graders use M&M's to count and then take away. They write number sentences to match their subtraction problems.

Help learners solve problems using multiplication and repeated addition. Using counters, learners will be paired up to solve problems. They will go through a series of questions and show models with the counters for the solution. Then...

Here is a math lab that helps young mathematicians understand the real-life meaning for vector addition. By building a model using spring scales and washers as weight, and then calculating the vector addition using two different methods,...

First graders listen to the book, So Many Cats, and discuss the number of cats in the story. They demonstrate simple addition problems using cat counters and a work mat in the shape of a house.

This lesson seems pretty advanced for K-2nd graders, but there are some pieces that can be used with young learners. Look through this comprehensive, fact-filled lesson and pull out information and activities that you can adapt to fit...

Research water use in California, environmental protection laws, and the proposition to raise Shasta Dam by 200 feet. Researchers use their findings to build an argument which will be presented at a mock decision panel. Groups then...

The lesson plan says it is intended for 4th grade but it is suitable for grades 1-3 as well. The class discusses what it means to add, the commutative property of addition, and mathematical reasoning. This is an exercise in number sense,...

Young mathematicians help Bobbie Bear pick colored buttons out of a box as they learn how to decompose numbers less than 10 into pairs of smaller numbers. To support young scholars with the process, consider creating a worksheet or...

Providing a step-by-step explanation of two-digit multiplication, a list of vocabulary words associated with this concept, and great examples, this resource would be a terrific classroom addition. Besides the set of of simple...

The size of a nanoparticle is difficult for pupils to grasp. A hands-on experiment is designed to give your classes perspective. Learners analyze different sports drinks for the content of electrolytes as an introduction to nanoscale....

Learners create patterns in a table to mimic the function of an electronic spreadsheet. The result is a table that creates an addition table for decimals in intervals of one-tenth. While creating the pattern, pupils must thoroughly...

Using their knowledge of the associative and commutative properties of addition, class members work with fact families to create two addition and two subtraction problems with three given numbers. 

Mathematics involves a study of patterns. The exploratory lesson has learners consider the addition pattern in different sets of numbers. Each set has a different pattern that pupils describe mathematically. The patterns involve...

Working on numbers 10 and 20? Don't forget your double ten frame! This double ten frame can also support addition and subtraction strategies and place value ideas. All on one page, ready to be printed and implemented as part of your math...

Reinforce math the concepts of addition, subtraction, multiplication, and division, with a six problem worksheet. Each question is presented in word problem format that requires learners to perform operations of numbers up...

Six questions make up a mixed practice worksheet. Scholars use their knowledge of addition, subtraction, multiplication, money, perimeter, ounces, and pounds to solve word problems with numbers up to 66,000.

Apply properties of operations to work with mixed numbers. The first of two lesson plans that focus on properties of operations works with mixed numbers and converting opposites of sums. Pupils work with properties of operations to break...

A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...

Six word problems make up this mixed practice worksheet. Pupils work with money, adding, subtracting, multiplying, and dividing using numbers up to 250.
