Round and Round
Learners interpret data from a three-dimensional array of current monitors to determine an overall pattern of water circulation. They hypothesize what effect an observed water circulation pattern might have on seamount fauna. A very interesting and high-level science lesson!
Multiplication Using Arrays, Number Lines, and Repeated Additions
An educational article can be as useful a tool as a good lesson. This article focuses on how one can use arrays, repeated addition, and number lines to reinforce a deeper understanding of multiplication. Links to 5 different worksheets are included.
Factors, Arrays, and Commutativity
Learners use desk arrangements to help them learn about factors, arrays, and commutativity. In this multiplication lesson, students read a multiplication problem about student desk arrangements. Learners then brainstorm a solution to the problem and watch the QuickTime video about the topic. Students complete the Commutative Operations handout and discuss. Learners may complete a factor pairs activity and a rectangular prism activity.
Number Story Arrays
Use these number story cards to give scholars practice with arrays and number models. There are 12 cards here, each with a simple object scenario for learners to apply mathematically. Mathematicians are given the number of rows and how many objects are in each row and then have to solve for the total number of the object. They draw the array and write a number model. The given numbers don't exceed 10, and some are written in word form while others are numeric. This could be an introduction to multiplication.
Array to Go!
Second graders are introduced to arrays as a means for multiplication readiness. Once students are comfortable with naming the array by counting the columns and rows, they integrate skip counting.
Adding Objects in Rectangular Arrays - Step-by-Step Lesson
These aliens will be familiar to any mathematicians who have seen Toy Story! Use an array of them to practice addition and writing number sentences. Because this worksheet includes the explanation to its one problem, project it as an all-class warm up. After examining the array, scholars write the corresponding addition sentence with its answer below. Note that the array doesn't necessarily make the intended number sentence clear, which is another reason you should guide learners through this practice.
Multiplication Strategies - A Day at the Zoo
This is an amazing 33-page resource for teaching multiplication! Your mathematicians will discover the connection between multiplication and repeated addition. They also will work collaboratively with arrays while studying zoo animals. It is recommended that you allow three class periods to complete all of the activities. Various strategies and manipulatives are suggested to make this a in-depth instructional piece.
Multiplication: Bugs Can Multiply, So Can I!
Develop multiplication skills with your class. Youngsters will visualize multiplication as repeated addition. Then they will create a multiplication bug book and discover arrays as a strategy for multiplication problem solving. Modifications are given as well as all of the resources that you will need. There are 37 pages in this well-designed packet. There is something for everyone to use!
Skipping Into Multiplication
Young mathematicians study the relationship between skip counting and multiplication. They build on skip counting skills and examine arrays while studying multiplication. Resources are provided.
Can you find them all?
For this Algebra II/Pre-calculus worksheet, students examine a 10 X 10 array and determine the pseudotrace of the array. The six page worksheet contains three problems. Detailed solutions are provided.
Let's Divide! - Grade Two
Math majors investigate problem situations involving the distribution of equal shares. Strategies such as repeated subtraction, array models and the use of manipulatives develop students' understandings of division concepts.
Multiplication Versus Addition
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.
Division by Fractions (Part Two)
Investigate division through the use of array models. The lesson focuses on using area models to compare division as sharing with division as grouping. Students evaluate the usefulness and limitations of the two array models.
Pupils identify and define various mathematical properties, such as the commutative properties of addition and multiplication, and the associative property of addition. They also reason and communicate mathematically by making mathematical connections. Finally, learners create their own simple array and exchange with a partner.
Division by Fractions (Part One)
Learners demonstrate array models to illustrate division as sharing and grouping. They demonstrate the array models to compare division as sharing with division as grouping. Pupils explore division problems are typically seen as either involving sharing or grouping.
Solar Kit Lesson #13 Solarize a Toy
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.
One Hundred Hungry Ants (Multiplication and Division)
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.
Solar Kit Lesson #13 - Solarize a Toy
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+ lesson, complete with background information, teaching notes, and student instructions.
Series or Parallel?
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.
Fact Families Lessons
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.
