Grade 3 - Multiplication Unit
Standards covered:
- 3.4 Number and operations
-
3.4D
Determine the total number of objects when equally-sized groups of objects are combined or arranged in arrays up to 10 by 10.
-
3.4E
Represent multiplication facts by using a variety of approaches such as repeated addition, equal-sized groups, arrays, area models, equal jumps on a number line, and skip counting.
-
3.4F
Recall facts to multiply up to 10 by 10 with automaticity and recall the corresponding division facts.
-
3.4G
Use strategies and algorithms, including the standard algorithm, to multiply a two-digit number by a one-digit number. Strategies may include mental math, partial products, and the commutative, associative, and distributive properties.
The Multiplication Unit involves identifying a variety of models to represent the process of multiplication in order to learn how to use it to solve problems. Questions to answer may include:
- How do multiplication situations differ from addition situations?
- How do equal-sized groups model multiplication situations in the world outside the classroom? What real-world examples of equal-sized groups can you think of?
- How do arrays and area models represent multiplication situations in the world outside the classroom? What real-world examples of arrays can you think of?
- Given a multiplication equation, how can you create a situation to match it?
Summative Assessment Task
Students determine the solution to 6 x 3 and draw a representation of their findings using circles and stars.
Instructional Tasks/Formative Assessments
Students determine if Amy will get the same total of pom-poms whether she buys packages of four pompoms or packages of seven pompoms.
Students create a story problem to match the equation 6 x 4 and determine the solution.
Using given information, students determine a math story and its solution.
Students determine if a problem matches 6 x 5.
The N/A classification refers to TEKS Standards that cannot be assessed through problem solving.
For this reason, tasks have not been included for these particular standards.
