In this lesson, students will explore problem-solving strategies through hands-on activities, including creating a flag with specific colors and calculating different breakfast combinations. The main mission revolves around Drew making a flag with three solid horizontal stripes (red, blue, yellow) and a gray star in the center. Students will also work with real-life scenarios, such as determining the number of unique breakfast combinations from various choices including eggs, bread, and juice. Engage in critical thinking and practical applications of problem-solving!

I will choose the best strategy to solve a problem. Main Idea/Vocabulary
DREW: I am making a flag to represent our class at the school assembly. The flag must have three solid-colored horizontal stripes (one red, one blue, and one yellow) with a gray star in the center of the middle stripe. YOUR MISSION: Find how many different flags Drew can make. Example 1
Understand What facts do you know? • You know that the flag will have a red, blue and yellow stripe. • You also know that a gray star will be in the center of the middle stripe. What do you need to find? • You need to find how many different flags Drew can make with three stripes and one star. Example 1
Plan You can use the make a picture strategy. Example 1
Solve Continue drawing flags until no more flags can be made. Example 1
Solve Answer:After drawing the flags, you find that 6 different flags can be made with 3 horizontal stripes with a star in the center of the middle stripe. Example 1
Check Look back by making a list of all the possible flags. RBY, RYB, YBR, YRB, BYR, BRY Since there are 6 items in the list and 6 different flags, the answer is correct. Example 1
