Video Investigation
Watch the "Multiplication Equations" video. Use the following pause points for discussion:
0:25 (Kittens): "How would we write '2 groups of 3' using math symbols?"1:00 (Birds): "Is it easier to count them one by one, or to count by groups of two? Why?"2:05 (Fish): ACTION: Have students complete Part 1 of their worksheet before the video ends. (Answer: 4 × 8 = 32).

Story Problem Creator
Students work in pairs to create a multiplication scenario. They must follow three steps on their worksheet:
Write a Story
Sketch Groups
Write Equation

The Gallery Share
Invite 2-3 pairs to share their story and drawing. Ask the class: "What are the groups in this story? How many are in each group?"
Common Misconceptions
Counting vs. Multiplying: Students may try to count every item. Encourage them to count the *groups* first.Order of Factors: Ensure students follow the [Groups] × [Items per Group] convention for this lesson.
