Solar Energy in New York
Middle schoolers examine a variety of information for New York State including insolation data, and economic or political data, thus incorporating both science and social studies. Encouraging learners to become concerned citizens as they enter the adult world, they get to consider whether or not increasing the amount of surface area devoted to photovoltaic system is a wise investment.
Fifth and sixth graders explore prime numbers. They work with a partner to build rectangular arrays using twelve tiles. Factor pairs are noted and recorded on graph paper. Pupils construct rectangular arrays with a prime number and conclude that there is only one possible factor pair.
Relate Multiplication and Division
Young mathematicians solve multiplication and division problems pertaining to the row and columns in arrays. This guides learners through a step-by-step process in understanding the concepts behind the math facts and also provides a chance to solve a word problem.
A great resource gets kids to start thinking about multiplication in a developmental way while building strong number sense and operational skills. Each slide contains scattered counters, which are then put into neat rows (making arrays), learners then write all the ways they can make that number, including multiplication and repeated addition. They complete three problems as a class and 5 on their own.
Introduction to Division
Examine how addition, subtraction, multiplication, and division relate to and are separate from each other. As they listen to the book, The Doorbell Rang, they demonstrate the math described in the story by cutting up paper cookies and write a short story incorporating three division problems. Cookie pattern is included in a link.
Adding Objects In Rectangular Arrays
These word problems have children use the provided images to solve word problems by adding objects in rectangular arrays. Use the raw material here, but edit the grammar and wording in the problems.
How Does that Work?
Sixth and seventh graders explore algebra word problems. They work with a partner to solve word problems distributed by e-mail. Learners simplify mathematical expressions following a "think aloud" algebra strategy modeled by the teacher. Many examples/worksheets are provided.
In this using arrays to solve a word problem worksheet, students read facts about a cheerleading competition and arrange the cheerleaders into different rectangular arrays. Students use numbers, words, and pictures to form arrays.
Area Model of Multiplication Using Base 10 Manipulatives
Explore two-digit multiplication with your class as they work in groups to build models of two-digit multiplication using base 10 manipulatives. They construct rectangles replacing standard numbers with equivalent place values using the blocks, and then relate their rectangles to the traditional written multiplication algorithm.
Double Your Flavor
Knowing your times tables in one thing understanding them is another. The class demonstrates their understanding of multiplication by skip counting, arrays, and moving manipulatives for the 0, 1, 2, 3, and 4 times tables. They watch a PowerPoint presentation, watch a teacher demonstration, construct a visual image for math facts, and fill in a multiplication chart. A quiz, the PowerPoint, and a rubric are included.
Get some competition going in your life science class. Give lab groups a variety of plant parts, all of them fruits, except one. Their mission is to make observations, compare and contrast, in order to be the first to identify the oddball. Through this exercise young biologists are exposed to homologous and analogous structures. The lesson plan is very detailed, including teacher and student instructions, a follow-up, and extension ideas.
Practice writing the same number sentence in a variety of ways. Learners will explore math cruise ship problems to write equivalent sentences. Then complete word problems which have been included in multiple languages.
Grade 3: Making Arrays
You will love this resource! Using a problem involving a farmer planting pumpkins, third graders create arrays to show the various maps the farmer needs to make to determine the number of pumpkins he'll be planting. The kids get to explore the concept of arrays in a real-life context. Using worksheets, 100s charts, and good problem solving skills, the class will really start to understand how an array represents multiplication.
"What are your personal media habits, and how much time do you spend with different forms of media?" are the guiding questions for an examination of middle schoolers' media use. Learners use the provided worksheets to create a personal Media Use Bar Graph and Media Use Log. The final discussion asks class members to consider the implication of what they have recorded.
Understanding Multiplication Using Arrays 3
Learners use arrays to understand the concept of multiplication better and solve problems. They solve four multiplication problems.
Understanding Multiplication Using Arrays 5
In this multiplication worksheet, students use arrays to write multiplication problems and then multiply them to find the answer. Students complete 4 problems.
Students investigate computer science as they study the semiconductor. In this technology lesson, students create a program in their computer class to build a simulation DLP using Java. Their output matches that of the program, while they explore ways to improve the semiconductor technology.
Review of Pointers
In this programming worksheet, students answer 50 multiple choice and true or false questions on functions and binary numbers.
Exploring Prime Numbers
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.
Third graders explore multiplication facts. In this multiplication lesson, 3rd graders examine methods for memorizing multiplication facts as they discuss and attempt 2 methods and play a multiplication game.
