This is very common at G6 level. A helpful memory device: 'PERImeter = PERIphery' (the outer edge). Another approach: have them remember that area measures SPACE (how much fits inside), while perimeter measures DISTANCE around. Use real examples—'How much carpet do we need?' (area) vs. 'How much tape to go around the edges?' (perimeter). Repetition with concrete examples works better than tricks alone.
Yes, units matter significantly by G6. Area should be in square units (square inches, square feet, cm²) and perimeter in linear units (inches, feet, cm). Require your student to always write units. This prepares them for higher math and helps them catch errors—if they write 'inches squared' for perimeter, they'll notice something is wrong.
Start by having them draw a dashed line to visually split the composite shape into two rectangles. Have them label ALL measurements they can see, then fill in missing measurements by using the fact that opposite sides of rectangles are equal. For perimeter, they trace only the OUTER edge (ignore the internal dashed line). For area, they calculate each rectangle separately, then add. Practice with 2-3 shapes before moving to more complex ones.
They're the same! This is an important concept at G6. Whether you say length=3 and width=4, or length=4 and width=3, the area (3×4=12 square units) and perimeter (2(3+4)=14 units) are identical. The shape just appears oriented differently. This helps students understand that area and perimeter depend on the actual measurements, not on what you call them.

This is normal at the medium-difficulty level. Teach them to find the MISSING measurements first. For an L-shaped figure, if they know some sides, they can use logic to find others (opposite sides of rectangles are equal, or segments add up). Have them fill in ALL measurements on the diagram before calculating anything. Then break the shape into rectangles and work systematically. This builds problem-solving skills beyond just plugging numbers into formulas.
