In this series of lessons, the concept of multiplication is introduced and students learn how to multiply by the numbers 2, 5 and 10.
In this lesson multiplication is introduced. It is defined as repeatedly adding the same number. The number of times one number is added is the same as the other number being multiplied.
In the problems in this lesson, students are given a multiplication statement and must write it as repeated addition.
In this lesson, students learn to use repeated addition to multiply single-digit numbers by 2, 5, and 10. They are given a multiplication problem and must write the number as repeated addition, then write the final result.
In this lesson, students learn how to count by the numbers 2, 5, and 10. They are given a starting number, a multiple of 2, 5, or 10, and must write the results of counting by that number.
In this lesson students count by a number, 2, 5, or 10, to do multiplication by that number. They are given a multiplication statement with 2, 5, or 10 as one of the factors and must write the results of the multiplication.
In this lesson, students learn how multiplication is represented using an array. The array is created as a visual way to represent repeated addition of the same number. The number of blocks in a row represents one factor in the multiplication. The number of blocks in one column represents the other factor in the multiplication. The total number of blocks in the array represents the sum.
Students are given an array and must write the multiplication statement the array represents then enter the product.
In this lesson, students receive additional practice multiplying by the numbers 2, 5, and 10.
