Maryland Grade 4: MCAP to MSTAR

Maryland is moving Grades 3–8 math from MCAP to MSTAR for the 2026–27 school year. The first spring MSTAR window is March 29–May 28, 2027; ask your school for its testing dates. See the official MSDE announcement.

The revised Maryland Grade 4 standards are being implemented in 2026–27. The official Grade 4 standards crosswalk explains the changes. Some existing worksheets are useful review or extension rather than current Grade 4 expectations: symmetry moved to Grade 2, and number and shape patterns moved to Grade 5.

These are Effortless Math skill-practice resources, not official MSTAR test questions or a complete assessment blueprint. Choose practice using your teacher’s current topic list. The collection has not been certified as covering every revised expectation.

A practical review routine

Choose one skill and start with a few questions. If the first examples feel unfamiliar, read the Quick Review together before continuing. Check the answers after the attempt, identify the step that caused trouble, and try a missed question again with the explanation covered.

Build a sequence when it helps: place value before multi-digit arithmetic, equivalent fractions before comparing fractions, and division before interpreting remainders in a story. Use the How to add and subtract fractions with like denominators when that step needs another explanation.

More Grade 4 support

The Grade 4 Online Center connects lessons and further practice. Start there when your child needs teaching before another worksheet.

If you are considering a book, review Mastering Grade 4 Math before choosing. Compare the sample with the topic your child needs and check the product page for format, price and purchase details.

For a focused word-problem book, review Mastering Grade 4 Math Word Problems and check its sample and purchase details before choosing.

For additional general problem-solving guidance, see How to solve multi-step word problems. Some examples go beyond Grade 4; choose those that match your child’s current work.
