Multiplication/Division StrategiesUnit of Study 12: Critical FCAT Review AreasGlobal Concept Guide: 2 of 3

Content Development When creating the Critical FCAT Review, we identified the areas

third grade students have previously struggled. Utilize current formal (Form 2 and Mock FCAT) and informal data when making instructional decisions. You may see other areas to address or choose to place higher emphasis on other topics based on your students’ data.

Please note the reporting categories and the weight each category holds on the FCAT.

Numbers: Operations, Problems, and Statistics 50%

Geometry and Measurement 30%

Fractions 20%

Content Development Make sure all problems are introduced in a real world context

as this will be the format used on FCAT.

Make sure to continue to teach multiplication and division together showing they are inverse operations, not teaching each in isolation.

Students may still need to continue using direct modeling of multiplication and division. Allow them to create these models as needed, but gradually move them towards pictorial representations and finally into number sentences and equations.

Content Development Make sure to incorporate a variety of problem structures. (Table 2 below comes from the Common Core State Standards of Mathematics)

Table 2. Common multiplication and division situations

Content Development Students need to be able to generate multiplication and division

equations and apply them to arrays, equal groups, linear models, and story problems.

Example:

[Type text]

2 pants x 3 shirts = 6 combinations

Khaki Pants Blue Shirt Blue Pants Blue Shirt Khaki Pants White Shirt Blue Pants White Shirt Khaki Pants Green Shirt Blue Pants Green Shirt

Students should be able to apply strategies for solving multiplication combination problems. If they are still struggling, they can draw models.

Content Development Students need to understand and utilize the Associative and

Distributive Properties. However they do not need to identify them by name.

Sample problem:

Raymond has 5 pictures of each of 3 types of ocean dolphins. He also has 4 pictures of river dolphins. The expression below represents the total number of dolphin pictures Raymond has.  (3 x 5) + 4 Which expression below also represents the total number of dolphin pictures Raymond has? A. 4 + (5 x 3) B. 3 x (5 x 4) C. (3 + 4) x (5 + 4) D. (3 x 5) + (3 x 4)
