What your child should master by the end of 4th Grade
By the end of 4th Grade, a child should multiply multi-digit numbers, divide with remainders, and reason fluently about fractions, including adding, subtracting, and multiplying fractions by whole numbers. Students extend place value to larger numbers and to decimals, and begin formal work with angles.
Key learning topics:
Multiply multi-digit numbers; divide multi-digit numbers with remainders
Use place value to read, write, compare, and round multi-digit whole numbers
Solve multi-step word problems; find factors and multiples; extend patterns
Build fraction equivalence and compare fractions; add and subtract fractions with like denominators
Multiply a fraction by a whole number; connect fractions to decimals (tenths and hundredths)
Measure and classify angles; understand lines, rays, and symmetry; classify triangles and quadrilaterals
Convert measurement units; solve area and perimeter problems
Proficiency looks like: a child who can multiply 36 x 24, add 3/8 + 2/8, and measure an angle with a protractor.
