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

First graders review number facts to illustrate the relationship between addition and subtraction. In this inverse relationship lesson, 1st graders write an addition sentence and then invert the numbers to show the subtraction fact.

Pupils complete activities to learn notation and uses for positive and negative numbers. In this number system activity, learners play a game similar to Jeopardy to learn how to solve problems with positive and negative numbers.

Eat your math manipulatives, are you serious? Yup, Learners listen to the story The M & M's Addition book, add single digit numbers to reach sums up to six, and demonstrate addition and subtraction number combinations using several...

In this math worksheet, students read about and learn the properties of addition. Students study the commutative, associative, identity and inverse properties. There are no problems on this page for students to solve.

Learners will add and subtract numbers less than 100 as well as understand and use the inverse relationship between addition and subtraction. They compose/decompose numbers up to 10 and understand a variety of situations in which...

Students multiply by one-digit whole numbers.

Second graders explore the inverse relationship of addition and subtraction in a "hands-on" activity based on the fact families of ones, twos and threes.

Second graders explore related multiplication and division facts. They study the inverse relationship of multiplication and division and engage in a group discussion about families. They complete a web-based lesson plan which is imbedded...

Learners solve basic multiplication or addition facts using a calculator and product cards. They draw a card, read the sum or product, and press single digits on the calculator to display the number on the card.

Young scholars explore regrouping. In this hands-on math place value activity, students construct models using connecting cubes and place value mats to solve simple addition problems that require regrouping.

Students create "fact families" using digital pictures of their classmates and knowledge of basic math concepts (subtraction and addition) in this technology-based math lesson plan intended for use in the early-elementary classroom. A...

Students play a team subtraction game, subtracting two-digit numbers and using addition to check their subtraction. They solve subtraction problems at the board while the team solves the same problem in their seats.

Pupils actively engage in the careful analysis of chromosome banding patterns and identify examples of inversion in homologous chromosomes.

Students solve problems involving electric charges and force. In this physics lesson, student solve word problems using addition and subtraction of vectors. They identify the direction represented by a vector as it relates to an electric...

Second graders, in pairs, use arrays to explore the relationship between multiplication and division.

Young scholars explore fact families. In this math lesson, students use links to model a fact family. Young scholars solve addition and subtraction problems.

Students fold paper to form a house, then use three numbers to make fact families for their houses. They write a family of multiplication and division facts on a piece of paper cut in the shape of a house.

Students participate in playing online games. In this practice lesson plan, students play online games to practice skills learned throughout the week.

Students subtract integers using counters. In this algebra lesson, students solve linear equations using an online tool. They use subtraction to isolate the variable.

Second graders read books about ice cream and plan an ice cream sundae party for the class. They research ingredients and determine how much the party cost each student. They hold a mock opening for an ice cream store and have their party.

Third graders use pennies as manipulatives to solve simple division problems. They create division number sentences to correspond with each exercise. This is a good, hands-on way to teach the concept of division.

Second graders accurately measure the distances they and their classmates jump. They determine the mean, median and mode of specific jumps. They are required to have two measurements for each classmate, one for standing long jump and one...

Second graders practice the multiples of three as an introduction to multiplying by three.
