Then, this can be written as an equation as: Since the number of marble that Chang has is unknown, we can give an arbitrary symbol, say x, to represent the same. In such real-world word, problems kid learn to formulate the equation by assigning a variable to the unknown factor. If Sher has 8 marbles, how many marbles does Change have? Application in Real World ProblemsĬhang has 7 times as many as marbles as Sher in their marble collection. Further, they can formulate the verbal comparison statements based on their evaluation. In other words, kids evaluate which one is the multiplicand and which one is the multiplier among the factors. Here, a similar bar model would of 4 groups of 3s topped on one another to form 12.Ĭomparing the representations of related equations, kids learn to evaluate which quantity forms a group and how many such groups exists. Now, consider the related multiplication equation 4 ×v3 = 12. In other words, 12 is 3 times as many as 4.

That is, 3 bars of 4s are topped one on the other two form the model. This can be represented using a tape diagram or bar model as shown: That is, consider the equation 3 × 4 = 12.

In grade 4, kids learn to formulate verbal comparison statements from multiplication equations and vice versa. In grade 3, they get familiar with the basic concept as well as they learn multiplication tables of one-digit numbers. Here, the numbers 4 and 5 are called the factors and the number 20 is called the product. The related multiplication equations are 5 × 4 = 20 and 4 × 5 =20. That is, there are 5 ‘groups of’ 4s or 5 × 4. Rectangular arrays were used to denote multiplication.įor example, the array below shows 20 dots arranged in 4 rows with 5 dots in each row. In grade 3, kids learned about the definition of multiplication as a repeated addition as well as using grouping strategy. Teaching Methodologies Multiplication as Comparison using Verbal Statements If the player lands on a prime number, he/she has to go back to 1 and start fresh.Īpart from these, there are many online multiplication apps and learning games for kids that can be used for practice the concept learned. When the die is rolled, the players start moving on the condition that a player has to find a factor other than 1 and the number itself while standing on a number. Teachers can help children to identify this number to be the factor pair of the considered factor.īoard Game with Primes and Composites: The game requires a 10 by 10 in which the numbers from 1 to 100 are written in order and a six-sided die. Once they find the factor pair, use skip counting by each factor to identify the number of factors counted to reach the product. The group can use the multiplication chart to find one of the factor pairs of the product given. The concepts taught using good math aids and reinforced using interesting kids educational games stays forever in kids’ minds.Īctivity using times table charts: Kids can be grouped into 7 groups and printable multiplication charts up to 20 can be distributed among the kids.Įach group can be allotted a times table and a product from the table. A 20 by 20 times table sheet would be helpful for finding the factor pairs of smaller numbers.Īrea Models: Area models can be used to explain the factor pairs which would be discussed in detail, later in the lesson. Times Table Chart: The kids can identify the factor pairs using a times table chart. Tape Diagrams or Bar Models/ Checkers, Coins: These can be used to show the grouping strategy for relatively smaller numbers.īlocks: Buiding blocks can be used to show the factor pairs as shown: Before advancing to multi-digit multiplication, grade 4 focuses initially on understanding the concept in a deeper sense. 3rd grade math deals with the two-digit multiplication of whole numbers.

One of the main agenda of grade 4 math curriculum is to develop the understanding and fluency with multi-digit multiplication.
