Fourth graders create arrays in a quilt based on the story Sweet Clara and the Freedom Quilt. In this quilt lesson plan, 4th graders discuss what the symbols in the quilt mean, along with making a quilt to show different areas of their school, and put new information in their KWL chart about the Underground Railraod.
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.
After analyzing objects arranged in rectangular arrays, youngsters write addition sentences to describe each. Model this for the class before they start, as the idea isn't completely clear. Note the third question may throw some students for a loop; they have to include zero as one of the addends. There are arrays with one, two, three, and four addends here. Ten problems total.
Students explore multiplication. In this multiplication problem solving lesson, students view a video clip which demonstrates loading a truck with packages. Students fill in a blank array to represent 1"X 2" and the multiples when increased by 10. Students solve similar problems to figure out how many packages would fit in the truck under different circumstances.
When math learners string beads on a pipe cleaner, they can represent their number of beads by separating them into 2 or 3 groups (10=1,9; 2,8; 3,7; 4,6; 5,5; 3,3 and 4; 2,5 and 3; etc.). They then draw some of the grouping configurations on a workbook page (not included). They follow a similar process with counters and share their groupings with the class.
Arrays are a visual way to practice multiplication and division. Using one of these twelve array picture cards, learners write a multiplication word problem describing what they see. After also recording a multiplication number sentence, they write a division word problem and number sentence. This will help learners connect the two math operations and visualize what they are computing. Laminate and cut out these cards for a math station!
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 instructional activity 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.
