Lesson 32 Homework | 4.5 __full__

Lesson 32 of Eureka Math Grade 4, Module 5 (referenced as 4.5) focuses on subtracting a fraction from a mixed number

: Subtracting a fraction larger than the fractional part of the mixed number (e.g., Common Strategies Subtract to Reach a Whole Number Example: To solve , decompose four-fifths two-fifths two-fifths Subtract the first part: Subtract the remaining part from the whole: Take from One Whole Example: For , decompose Subtract from the whole: Add the results together: Step-by-Step Problem Solving (RDW Process) The curriculum encourages the Read-Draw-Write (RDW) process for all homework problems: the problem carefully. lesson 32 homework 4.5

• For each problem in 4.5: a. Read the problem fully, underline the target (solve, simplify, differentiate, factor, etc.). b. Decide which method applies (e.g., factoring vs. quadratic formula; common denominator for rational expressions; product/chain rule for derivatives). c. Write the plan in one sentence (e.g., “I will factor the trinomial, set each factor = 0, and check extraneous roots.”). d. Carry out steps neatly, showing algebraic work or derivative steps. e. Box the final answer and, if applicable, check (substitute roots back, simplify numerically, take derivative again from first principles for a quick sanity check).
• If you get stuck after 5–8 minutes on a problem, skip it and return later.

• Magnitude: Is ( \frac78 ) closer to 0 or 1?
• Addition as movement: Adding means moving right.
• Mixed numbers as natural points: ( 2 \frac14 ) is exactly between 2 and 3.
