Learners 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.
Here's a delicious approach to rectangular arrays which will have your scholars learning all about Peeps. They visit the online Peep headquarters to watch a history of the treat and take a virtual factory tour. Discuss why Peeps are packaged the way they are and connect this to rectangular arrays. Partners use a handout to guide them in creating their own arrays and describing them using addition and multiplication sentences. They explain the counting pattern their array demonstrates and write the related fact family. Allow scholars to apply these skills as they package various items. How many can fit in the box? They finally revisit the website to take a quiz.
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.
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.
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+ instructional activity, complete with background information, teaching notes, and student instructions.
Have fun building mathematical proficiency by engaging children in a math game! All you need to do is print the game board, playing cards, and instructions and let those kids have some fun. They move their pieces around the board in order to conquer or take each square, the trick is they can't take a square until they divide double-digit numbers and show their work. They practice writing equations, using arrays, or drawing an area model to complete each problem. Even your most reluctant mathematicians will love this game.
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.
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.
Fourth graders play a game with red and green cards (composite and prime numbers). As a card is drawn students create all possible arrays. The winner of each round is the person with the most arrays. Students discuss their results, and define the terms prime and composite.
