In this multiplication with 3 activity, students find the products that multiply with the number 3. In the second set, students draw an array for each problem and then complete the multiplication sentence. Students finish with two test prep questions that multiply and divide by 3.
Review multiplication facts and concepts! This clear, and easy to follow lesson will help your class to understand multiplication by using arrays and repeated addition. There are strategies to help with memorization and manipulative suggestions.
After hearing the story, One Hundred Angry Ants, learners apply what they have seen to a math challenge. They choose one of three numbers: 12, 24, or 36. Imagining this were the number of ants going to a picnic, they consider how many ways these ants could arrange themselves into equal rows. Learners demonstrate their conclusions visually through drawing an array. They find multiple solutions until they can explain why there are none left.
Each of these number sentences has a corresponding set of blocks, which will no doubt help your visual learners grasp multiple-addend addition. Learners examine the sentences and match them to their block representation. Consider also having them do this with math manipulatives, creating different designs and writing equations to match. All of these addends are single-digit, and there are five problems.
Students and teacher talk about arrays of numbers like the ones in A Square of Circles. They check to see that the rows all have the same sum; that the columns all have the same sum; and that the diagonals have the same sum.
Fourth graders define prime numbers and examine which numbers are prime numbers. They access prior knowledge to show multiples in an array. Pupils play a game to determine which numbers are prime numbers.
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!
Fourth graders use properties of operations and problem-solving strategies to do mental calculations, and look for patterns in the solutions. They create an array, using each of the digits 1-9 exactly once to form addition problems consisting of two three-digit addends and a three-digit sum. Students record the strategies they used to find solutions.
You will love this resource! Using a problem involving a farmer planting pumpkins, third graders create arrays to show the various maps the farmer needs to make to determine the number of pumpkins he'll be planting. The kids get to explore the concept of arrays in a real-life context. Using worksheets, 100s charts, and good problem solving skills, the class will really start to understand how an array represents multiplication.
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.
Second graders create arrays to study multiplication. In this multiplication instructional activity, 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 instructional activity and use grid paper to explore creating arrays.
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.
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.
In this multiplication array worksheet, student color or shade arrays to match the five times table problem at the bottom of the page.
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.
Third graders use items which come in sets to look for real-life multiples and write multiplication problems. This instructional activity assess the student's understanding of the meaning of multiplication using an array model and manipulatives.
In this finding the products instructional activity, students use arrays to write two multiplication facts and then draw arrays to calculate multiplication equations. Students solve 20 problems.
First graders explore multiplication concepts through skip counting, repeated addition and arrays. Using animal characteristics as a context, 1st graders solve problems using mathematical tools such as hundreds charts, number lines, counters and drawing arrays that represent the problem situation.
Third graders practice modeling multiplication facts with Digi-Blocks on their array mats. As a class, they complete the x1, x2 and x3. With a small group, 3rd graders complete multiplication facts to 10x10. Facts are recorded on their activity sheet.
Students build models of rectangular arrays with blocks. They separate the arrays along place value lines to identify partial products. Students record partial products. Students find the total value for each array.
