An interactive math lesson illustrating the relationship between multiplication and The same result can be obtained by repeated addition. Game, What is it?. Bridging Multiplication and Addition Partner Practice artsocial.info Students will explain the relationship between the array and multiplication word problem. Learn whether multiplication is really repeated addition and what it means to Relationships In other words, 3 x 2 is the same as 2 + 2 + 2, which of course is 6. the idea of repeated addition to help explain the meaning of multiplication.

Record four equations for some of these. Take one of these groups, for example 3, 4, 5.

Relating division to multiplication

This will show that the third number is 7. Conclude that 5 can be changed to 7. Explore the other options of changing one of the numbers: Explore one more example, for example 4, 7, Discuss that instead of 10 this number should be Alternatively, model seven and highlight the fact that the 4 could be changed to 3. Ask, is there a third thing we could do? Change 7 to 6. Continue to make available to the students, digit cards, cards with addition, subtraction and equals symbols, tens frames and counters, paper and pencils.

Have students pair share their recordings. Discuss what is the same or different about them this depends on which number they change.

They should draw a box around sets of four equations that they have written that are the same as a partner has recorded. Activity 3 Conclude this session by summarising on the class chart, the features of a family of related facts: Write and read sets of related addition and subtraction equations.

Explain, in their own words, the inverse relationship between addition and subtraction. It is not necessary for students to know the name for this.

Activity 1 Begin by reading together the concluding notes from Session 1. Distribute sets of Family Shuffle cards Attachment 1 to students. To recognise related addition and subtraction equations Explain how to play. Each student has one set of 16 shuffled cards. These are dealt out, face up, in a four-by-four array. Two cards any are removed from the array and set aside, creating two empty spaces in the array.

The two cards that were set aside are replaced to complete the array. Students could write their own sets to create alternative puzzles. Ask students what they notice about what is happening with the numbers. Read to the class or have written on the class chart this scenario. Discuss what is happening in these equations. Have you heard anytime that addition and multiplication are related?

If no, then you students can use this skill to improve your math multiplication.

Many students find it difficult to multiply the numbers, but if you practice this skill to hone the multiplication skills, you will find it easy to solve various multiplication problems. Multiplication is also known as repeated addition.

This explains everything about how addition and multiplication are related. However, to understand it in a better way, we will consider few instances.

It is described in next paragraph. Understanding the Relation in a More Lucid Manner: Let us consider an instance that, there are three students. To do this, we have to find the total number of students in 3rd grade.

There are 4 classes with 16 students in each class. How many popsicle will we need? You could substitute popsicle for anything that you may be giving the students. The teacher asks students to give ideas on how to solve the problem. If student responses indicate repeated addition, the teacher should respond "How else can we do this without adding over and over?

The teacher will ask students if they remember how to make an array? Then, the teacher will ask, "Do you think an array can help us solve this problem? Then, the teacher will ask the students, "What is a row? The teacher will ask students "How many operations are there in math that we work with? The teacher will ask students to make a prediction on which operations they can use to solve the popsicle problem.

The teacher will write predictions on the board. What activities or exercises will the students complete with teacher guidance?

The teacher tells the students that they are going to do a group activity to solve the popsicle problem. The teacher reminds the students of the rules for group activities such as, treat others respectfully, value all ideas, don't interrupt a speaker, listen to all the speakers, and raise your hand if you have a question or don't understand something. The teacher will write the popsicle problem on the board and tell the students we are going to explore how to solve the problem without adding over and over.

The teacher will give another student a stack of question cards see attachments. The teacher will have that student read and answer question card 1 "What is the problem telling us? That student will then pass the stack of question cards to another student who will read question 2 "What are we trying to find?

Repeat for question 3 "How many groups do we have? Examples of what the board may look like are provided below. The teacher will then ask the students "Do we have enough information to solve the problem? The teacher will ask the students, "How many in each group? The teacher will have the recorder fill in the array. The teacher will ask the students if there is a strategy we can use to find the total amount, other than counting each dot. The teacher is looking for students to separate the array into sections; they know e.
