Elementary schoolers explore prime and composite numbers. They use tiles to create arrays and work with a partner to find as many array combinations as possible from their assigned numbers. Pupils create a t-chart of prime and composite numbers and construct a 100's chart to tell if a number is prime or composite.
Students explore the array model of multiplication. They read the book, "One Hundred Hungry Ants," form sets with Unifix cubes, write problems using multiplication, and create a concrete example of the array model using toothpicks.
Students explore multiplication. In this multiplication problem solving lesson plan, students view a video clip which demonstrates loading a truck with packages. Students fill in a blank array to represent 1"X 2" and the multiples when increased by 10. Students solve similar problems to figure out how many packages would fit in the truck under different circumstances.
Elementary schoolers use arrays to help find quotients, divide two-digits by one-digits, and solve word problems. They solve twenty-three problems.
Fifth graders apply math to real-world situations. In this mathematics lesson, 5th graders are read the book, "Math Curse," which discusses ways in which math is used each day. Students then write a sequel to the book in groups, brainstorming their own math problems that could be encountered. Students make both a rough draft and final copy of the class book.
Going to the pumpkin patch? Start with this multiplication lesson plan using pumpkin arrays and factors between 1 and 10. As you project a hundred chart, learners use their own (handout included) to map out a farmer's field. First, he plants three rows with ten pumpkins in each. Then, he plants ten rows with six pumpkins in each. Learners record the equations in the provided worksheet, and watch for patterns when dealing with 10 as a constant factor. Follow-up activities are provided.
Second graders write and solve story problems which involve whole numbers, using addition, subtraction, multiplication, or division. They solve multiplication problems by using strategies other than counting all. They interpret and solve multiplication story problems.
In this math challenge activity, students examine the pictures of 3 American flags and respond to 3 questions that require them to identify arrays.
In this making equal groups worksheet, students, working with a partner, study and calculate how to make equal groups through six word problems.
Second graders participate in a math game that allows the students to practice their multiplication skills, and reinforces the 'array' concept of multiplication. They perform multiplication calculations using numbers one to six and record their answers on a grid.
In this mathematics worksheet, 6th graders estimate the product and use an array to help them find the product. Then they find the exact product and locate where to put the decimal point in each.
In this multiplication worksheet, students analyze arrays. Students write the multiplication fact that goes with each array. There is an example.
Fifth graders use prime factorization to identify prime and composite numbers. They use cubes to find factors. In groups, 5th graders draw rectangular arrays to discover prime numbers under 100.
In this other algebraic patterns worksheet, 9th graders solve 10 various types of problems related to determining the pattern in the graphs shown on the sheet. First, they complete the table for arrays with the height and cubes given. Then, students how the function rule developed compares to function rules found in linear data sets and also, graph the results.
In this ESL math terms learning exercise, 3rd graders learn the meaning of: skip counting, repeated addition, drawing an array. Students draw lines to match six words with the pictures that illustrate them.
Second graders model multiplication facts on a multiplication grid. They use the hundreds array to find groupings, known facts to solve multiplication facts. Students demonstrate the ability to use the multiplication facts. They are given blank multiplication grids.
In this mathematics worksheet, 6th graders find the product of a given equation. Then they use an array and find the sum of the partial products. Students also use zeros as place holders when necessary.
In this multiplication arrays worksheet, students analyze 5 arrays and write both an addition and a multiplication sentence for each.
Elementary schoolers solve six number sentences by utilizing arrays and then complete six number sentences using both multiplication and division.
