A field trip has 5 buses with 46 students on each bus. At the museum, 18 students join from another school. How many students are at the museum?
Reasoning strategy

Difficulty Practice Guide
Medium Grade 4 Word Problem Mixed Word Problems
This page shows what medium practice should demand for grade 4 word problem mixed word problems. The goal is not a larger worksheet. The goal is to make the student's reasoning visible enough to choose the next better problem.
What Changes At This Difficulty
Add one meaningful reasoning layer so students must plan before calculating.
Expected structure: 3-3 step problem solving.
Vocabulary load: medium with intentional distractors.
Reasoning depth: at least 3 relationship layers.
Student Work Signals
A good medium problem should expose the bottleneck
MathRoutine watches for whether the student understood the situation, wrote a useful setup, handled the calculation, and answered the exact question asked.
1
separate useful numbers from background details
2
complete a two-step setup
3
interpret the result with the correct unit
Sample Problems
A school bought 9 boxes of notebooks with 24 notebooks in each box. After giving 37 notebooks to teachers, how many notebooks are left for students?
Reasoning strategy
Find the total notebooks first, then subtract the teacher notebooks.
Why This Matters
The paid value is diagnosis, not answer lookup
Basic gives repeated targeted practice. Pro becomes useful when the student needs help understanding wording, recovering the setup, or seeing the same misconception return across attempts.
