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!
Students use desk arrangements to help them learn about factors, arrays, and commutativity. In this multiplication lesson plan, students read a multiplication problem about student desk arrangements. Students then brainstorm a solution to the problem and watch the QuickTime video about the topic. Students complete the Commutative Operations handout and discuss. Students may complete a factor pairs activity and a rectangular prism activity.
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.
Physics classes that are studying electricity connect photovoltaic cells into both series and parallel circuits. Inquiry and critical thinking come into play as learners try to determine which circuit is more productive. They associate their findings to the design of PV arrays. A thorough explanation is provided for the teacher, as well as lab sheets for the students.
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.
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.
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!
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.
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.
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.
Learners 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.
