Summative Assessment (End of Lesson)

Students will demonstrate their mastery of the lesson by accurately solving multiplication facts, division facts, one-step word problems, and a missing-factor equation, showing that they can apply their understanding of basic operations to real-world and numerical situations.

10-question mini-assessment:

  • 4 multiplication problems (mixed facts)
  • 3 division problems
  • 2 word problems
  • 1 missing factor equation

Example Items:

  1. 7 × 6 = ___
  2. 21 ÷ 3 = ___
  3. A pet shop has 5 cages with 8 birds each. How many total birds?
  4. Fill in the blank: __ × 4 = 24

Rubric:

  • 4 = Meets with mastery
  • 3 = Meets
  • 2 = Approaches

1 = Does not meet

Post-test

Same format as pretest (but different numbers) to measure growth.

Includes:

  • One array item
  • One equal grouping item
  • One strip diagram
  • One missing factor
  • Two-word problems

Common Misconceptions

  1. Confusing “number of groups” with “number in each group.”

    Fix: Use labeled diagrams or sentence frames (“___ groups of ___”).

  2. Thinking about multiplication always makes bigger numbers.

    Fix: Use 1× or multiplying by 0 examples.

  3. Division is interpreted only as sharing, not repeated subtraction.

  4. Students reverse factors in arrays (“3 rows of 5” vs “5 rows of 3”).

  5. Believing that multiplication and division have the same operation direction.

    Fix: Connect with fact families and arrows showing opposite operations.
