Students understand for both multiplication and division groups are always equal.

TEKS: Multiplication and Division

Number and operations. The student applies mathematical process standards to connect repeated addition to multiplication situations that involve equal groupings and shares.

The student is expected to:

Equal groups that are added (multiplication) or equal groups that are subtracted (division)

(A) model, create, and describe contextual multiplication situations in which equivalent sets of concrete objects are joined; and (repeated addition) 2 x 3 (2 how many groups and 3 how many in each group)

(B) model, create, and describe contextual division situations in which equivalent sets of concrete objects are separated and (repeated subtraction) 6 divided by 2 Six is the whole and 2 represent the number of groups How many in each group?


Students understand multiplication can be represented by adding equal groups.

Students can transition to creating a visual representation (bar models) using Unifx Cubes as groups (boxes, bags, people,etc). Each cube represents the SAME amount..students will use repeated addition to find the total.

To find how many in EACH group students can use doubles..

Students have a clear understanding that multiplication is represented by using EQUAL groups.

GIVEN: Total and number of groups FIND: How many in each group.
Big picture

Division can be represented by subtracting EQUAL groups.

Students will count on EQUAL groups to achieve the total.

Given: Total, how many in each group and some of the groups.

Goal: To find how many groups in all.

Students will use the visual support given to find the number of groups needed.

Students will use cubes to count on to get to the total.

Students will draw the missing cubes.

Students will use both the related multiplication fact and repeated addition.

'8 groups of 3 make 24.'
