Practice solving expressions using the order of operations (PEMDAS/BODMAS) with addition, subtraction, multiplication, division, and simple exponents.

Remind your child that multiplication and division have equal priority in PEMDAS, so they should work from left to right when both appear in the same expression. Practice with simple examples like 12 ÷ 3 × 2, showing that we do 12 ÷ 3 = 4 first (because it's on the left), then 4 × 2 = 8.
Start by reviewing what exponents mean - that 3² means 3 × 3 = 9, and 2³ means 2 × 2 × 2 = 8. Practice calculating these simple squares and cubes separately first, then show how exponents are calculated right after parentheses in PEMDAS, before any multiplication, division, addition, or subtraction.
Ask your child to explain why they're doing each step and what would happen if they did operations in a different order. True understanding shows when they can predict that 2 + 3 × 4 equals 14 (not 20) and explain that multiplication must be done before addition.
Teach them to imagine reading a book - we read from left to right, and that's exactly how we handle multiplication/division and addition/subtraction when they appear together. You can also have them underline or circle operations from left to right before solving.

Separate the two skills - praise them for following the correct order of operations, then focus on the basic math facts separately. Consider having them double-check their arithmetic with a calculator after they've determined the correct sequence of steps, so they can build confidence in the PEMDAS process.
