Students balance number sentences to learn about missing values. In this balanced equations activity, students use the word problem to study missing values. Students watch a video about the topic and play two games about balancing equations with multiple terms as well as solving equations for missing values. Students then complete a worksheet about missing value equations. Students finish with two assessments for balancing equations.
Practice using problem solving strategies by breaking down word problems into a series of visual "stair" steps. Learners restate what is being asked, locate word clues, eliminate unnecessary information, and determine the operation to be used. They practice this strategy independently by completing a related worksheet.
Second graders start thinking about compensatory numbers and how they can be used to subtract without regrouping. They work through a series of four activities that span several days and engage them in pair work and problem solving with manipulatives. Real world math problems and problem solving strategies are heavily focused on in this complete and well thought out resources.
Clarify prime numbers, composite numbers, and prime factorization with this worksheet. After looking over definitions, working through prime numbers, and making composite numbers, learners are introduced to prime factorization and the Sieve of Eratosthenes. This resource includes a homework assignment in which mathematicians respond to 7 short answer questions that ask them to solve, identify, and explain mathematical concepts in their own words.
Solve division problems by using strategies with your class. Scholars will explore how to divide whole numbers by 5. They perform guided practice worksheets and play whole class games to practice this skill. This lesson includes worksheets, an evaluation, and an assignment and is 5 pages long.
Turn your math lesson into a carnival game with this fun, outdoor activity. After reviewing the concept your class will be practicing briefly, split your class up into teams and head outdoors. These teams work to solve math questions and are rewarded for each right answer by popping a balloon filled with prizes! Although this lesson uses word problem involving the basic operations of adding, subtracting, multipling, and dividing, this motivational activity could be adapted for any material.
Bring some sweet fun to your math class (you can use sugar-free cookies also)! Pupils practice division and remainders with the assistance of a bag of cookies as manipulative's to assessing the concept of whole numbers. In groups, they create their own division problems that they eventually present to the rest of the class. Great ideas are presented.
Students in second grade are paired with fifth grade computer research buddies. They observe the characteristics of caterpillars, and identify the four stages of the caterpillar to butterfly life cycle. They graph the number of butterflies that hatch from chrysalis over the course of a week using web resources. They design a PowerPoint presentation.
Fifth graders use interlocking cubes to build towers to represent factors of numbers and place the towers in the appropriate places on a Tower chart in order to look for patterns. They work in partner groups, and finish by writing statements about prime numbers, composite numbers, and patterns they noticed during the activity.
First graders are introduced to addition with the help of the book, "So Many Cats," by Beatrice Schneck de Regniers. They practice whole numbers by counting cats in a story and in pictures by identifying, and comparing whole numbers as well. Each student recognizes that addition is the progressive accumulation of a given object.
Second graders calculate mileage for a journey. In this place value and measurement instructional activity, 2nd graders read Johnny Appleseed, work in groups to locate his birthplace on a map, locate the other states he stopped in, and measure the distance between each stop. Students calculate the mileage needed for Johnny Appleseed's journey and discuss the place value of each number.
Brainiacs explore the concept of solving single-variable equations.They use inverse operations to solve equations, and participate in activities such as balancing an equation scale. This is an awesome lesson, complete with game transparencies, worksheets, and multiple pdf attachments.
In this Sudoku-style activity, mathematicians place various rational numbers into their appropriate places. Addition, subtraction, and multiplication of a mix of fraction and decimals are required. Add this to your curriculum as a homework assignment when teaching operations with rational numbers and when your learners are working toward attaining seventh grade Common Core discrete skills.
