Second graders create arrays to study multiplication. In this multiplication lesson, 2nd graders split into teams to complete a multiplication table. One team uses addition to solve the table while the other uses multiplication. Students watch a video for the lesson and use grid paper to explore creating arrays.
Investigate division through the use of array models. The lesson focuses on using area models to compare division as sharing with division as grouping. Learners evaluate the usefulness and limitations of the two array models.
Students work in teams they select a low-power toy, game, or electrical deive to "solarize," or convert to solar power. They determine the operating voltage of their chosen device and design a solar array to provide this level of voltage. Pupils determine a series of conditions under which they test their toy's performance and, if needed, adjust the size of their solar array to provide more current.
Fourth graders explore factors of numbers from 1 to 50. They gain practice with basic facts and multi-digit multiplication problems. Students practice the commutative property. They discover the link between multiplication and division. Students demonstrate using rectangular arrays to symbolically solve problems.
Physical science or technology classes will be invigorated by this challenge: to convert a toy, game, or other device to run on solar power. In doing so, they will design the appropriate solar arrays. This is an A+ activity, complete with background information, teaching notes, and student instructions.
Emerging electricians extend mental models of light bulbs and resistors in series and or in parallel circuits to include the connection of photovoltaic cells in arrays. They investigate open circuits, using a DC voltmeter, a light source, and photovoltaic cells.
Have you ever tried using arrays to help you teach the fact families that go with multiplication and division? If not, you should read this article! Some excellent and easy-to-implement ideas are presented, along with some good lessons which are linked at the bottom of the page.
Third graders use items which come in sets to look for real-life multiples and write multiplication problems. This lesson assess the student's understanding of the meaning of multiplication using an array model and manipulatives.
These acitivities are designed for two! With a partner, problem solve and calculate the answers to fifteen word problems or mathematical equations. Scaffolding and coaching are included, and as an extension learners are prompted to create their own problems to illustrate with arrays and equations. 
Students practice arrays using prior knowledge. In this patterns lesson, students explore the patterns of squares and cubes and record their findings. Students discover the patterns and share.
Fifth graders discover the connections between algebra and geometry. With a focus on arrays and factors, they are introduced to multiplication. They develop an array for multiples of 2 through 10 and identify the factors of each row. They also discover patterns and complete a worksheet to end the lesson.
First graders explore multiplication concepts through skip counting, repeated addition and arrays. Using animal characteristics as a context, 1st graders solve problems using mathematical tools such as hundreds charts, number lines, counters and drawing arrays that represent the problem situation.
Students study the use of the Commutative Property and arrays. In this Commutative Property and array lesson, students watch a teacher demonstration of the use of arrays using a set of cans. They discover the Commutative Property of multiplication during the lesson, and practice making arrays with stickers.
Third graders practice modeling multiplication facts with Digi-Blocks on their array mats. As a class, they complete the x1, x2 and x3. With a small group, 3rd graders complete multiplication facts to 10x10. Facts are recorded on their activity sheet.
Third graders play a game on the computer called "Last Array" where they practice their multiplication skills. In this multiplication lesson plan, 3rd graders try to be the last person to place an array on the computer screen.
Fourth graders demonstrate multiple ways to represent whole numbers, decimals, and fractions. Through demonstration and hands-on activities they model square numbers using arrays. Students visually determine that the array makes a square.
Students build models of rectangular arrays with blocks. They separate the arrays along place value lines to identify partial products. Students record partial products. Students find the total value for each array.
Students practice using the commutative and distributive properties of mathematics to solve problems. They split an array into two smaller ones with the distributive property. Students also demonstrate an understanding of number relationships and functions.
Students use counters to review arrays and multiplication and learn arrays and division. For this multiplication and division lesson, students use counters to arrange multiplication equations and division equations.
Help the class determine missing factors in equations by creating arrays. Through modeling and practice, they come to see the inverse relationship between multiplication and division. As an assessment, individuals build their own array and write corresponding equations.
