Start with Grade 4 Math Practice
Use this general Grade 4 math practice test to check your skills, then review the missed topics below. It is independent practice, not an official state assessment or a replica of its timing, scoring, or question types.

Arizona Grade 4 math: Keep the unit whole fixed when adding mixed numbers
Use a worked problem to connect a calculation with its meaning. The selected references below come from Arizona’s official Grade 4 mathematics document, linked in the state mathematics directory.
Join two ribbon lengths
In this original example, a ribbon is 2¼ meters long and another is 1¾ meters long. What is their combined length? Each whole is one meter, and each fractional part is measured in quarters of that same unit.
Add the whole-number parts: 2 + 1 = 3. Add the quarter parts: ¼ + ¾ = 4/4 = 1. The combined length is 3 + 1 = 4 meters. An equivalent calculation uses improper fractions: 9/4 + 7/4 = 16/4 = 4.
The colors separate the two ribbons; each meter has four equal parts. The drawing is a unit model, not an actual ribbon to measure on the screen.
Explain why the denominator stays four
A response of 3 4/8 changes the size of the fractional unit. Four quarter-meter pieces make one meter, not half a meter. The denominator names the unit pieces; adding their counts does not turn quarters into eighths. Likewise, ½ meter can be shown as 2/4 meter by dividing the same one-meter whole into more equal parts.
Use the model to decide what to review
If the student finds 4/4 but leaves the answer as 3 4/4, ask how many wholes the four quarters make. If the student changes the denominator, return to the equal parts in one meter. If the student adds correctly but cannot explain ½ = 2/4, compare two partitions of an equally sized whole before changing to a new denominator.
- Name the whole and the fractional unit before calculating.
- Show both lengths using quarter-meter pieces.
- Join the pieces, regroup a full meter, and write the result with a unit.
- Check using improper fractions or estimate that 2¼ + 1¾ is close to 4.
For the next session, use the topic directory’s equivalent-fractions or mixed-numbers row. Choose its lesson first, then the worksheet or quiz according to the learning need the explanation reveals.

Fraction study questions
Why is ¼ + ¾ equal to one whole?
Both fractions count quarters of the same whole. One quarter plus three quarters makes four quarters, which is one whole.

Arizona AASA Grade 4 Math FAQ
What is the AASA Grade 4 math test?
The AASA (Arizona's Academic Standards Assessment) is Arizona’s Grade 4 mathematics assessment. The linked activities are independent Grade 4 practice. Their question count, timer, scoring, and item types may differ from the official assessment. Use the directions inside each activity.
Can I use a calculator?
Calculator rules depend on the grade, assessment, test segment, and approved accommodations. Follow the current assessment guidance and ask your school which rules apply. A tool available in independent practice does not establish permission on the official test.
How long is each practice test?
Read the timer and question count shown in the practice activity you open. These are practice settings, not a statement of the official assessment’s duration or scoring.
Is it free?
The linked general practice and topic resources are available separately from optional books. Check each activity’s directions and access requirements. The study guide and bundle are optional next steps.
