In this computer programming review worksheet, students answer 50 multiple choice questions on one and two dimensional arrays.
Tiling is a great method to use when introducing young mathematicians to the concept of area. In the second video of the series, this process is clearly modeled both by laying down unit squares in arrays and by drawing lines to create arrays within rectangles. Extend the instructional activity by passing out various sizes of rectangles and asking young learners to find their areas using square tile manipulatives. When asking children to draw lines to create arrays in rectangles, consider providing rulers as additional support.
Students explore the challenges that are faced when transporting materials into space. They review the various forms of energy, including solar arrays, that are used on the International Space Station and how generating this energy calls for collaboration between researches on earth and in space.
Learners practice multiplication concepts. In this multiplication instructional activity, pupils make arrays by using counters and solve various multiplication questions. They model arrays with counters for reinforcement.
In this optical array lesson, students read a scenario that asks them to design the layout of an optical sensor using an ice cube tray. Students must come up with a design that will maximize the space using geometrical shapes. This link includes an attached printable version of the lesson.
Here's a great way to learn about the powerful multiplication strategy of using arrays. A review discusses multiplication in terms of repeated addition, grouping, and as arrays. Then, two examples illustrate how to figure out word problems by drawing an array. This is the second of five videos about interpreting products of whole numbers.
An array acts as the vehicle for learning a powerful multiplication strategy–counting in patterns to multiply. With a step-by-step visual breakdown of multiple methods for counting a 4x2 array, learners see that there is more than one way to solve a problem. As the first video of a five-part series, the lesson does a lot to scaffold learning that will come later.
How do arrays relate to area? Learners use prior knowledge about arrays to think about finding the area of a rectangle in the first of two videos on relating area to multiplication. The resource points out the common error of adding the length and width unit instead of multiplying them.

In computer programming, loops and arrays seem to be made for each other. This video describes how to add a while loop to print out each element in an array, and then doing the same procedure using a for loop.
Fifth graders use arrays to show the meaning of multipication in selected situations. They practice using large and small arrays. The instructional activity has numerous activities, which gives students more opportunities to display academic growth.
Students create arrays using Microsoft Excel. In this technology-based math lesson, students expand their knowledge of multiplication by creating arrays on the computer using a spreadsheet program such as Microsoft Excel.
Fourth graders participate in a lesson plan that focuses on the skill of multiplication. They practice using arrays to display multiplication using two digits and then write the corresponding number sentences.
Students participate in a lesson that is concerned with the concepts of arrays and factors. They use a Hershey bar and divide it into segments in order to simulate the arrays. Then students construct other arrays from the leftover pieces.
Fifth graders examine multiplication. They construct arrays to demonstrate specific multiplication facts. They identify examples and non-examples of arrays. Students use counters to model the commutative property of multiplication.
Students explore the concept of estimating and organizing a group of objects into an array to count the exact number of items. They create their own arrays and practice elements of estimation.
In this making arrays worksheet, students, working with a partner, study and calculate how to make arrays by completing six exercises.
Students recognize patterns in arrays and repeat these patterns back to the teacher. They determine and tell the teacher the total number of squares in the array based on the pattern they recognize.
Twelfth graders compare and contrast variables and arrays. Using data, they enter the information into a spreadsheet and an array to compare how they appear. To end the lesson, they complete basic programs in which they use arrays.
