Where grade 4 students often struggle
- Adding fractions by adding denominators (1/2 + 1/3 ≠ 2/5)
- Forgetting to regroup in multi-digit multiplication
- Comparing decimals incorrectly (0.45 > 0.5 because 45 > 5)
- Not checking if answers make sense
- Confusing factors and multiples
Signs your child is on track
- Estimates before calculating to check reasonableness
- Explains fraction equivalence with pictures or reasoning
- Connects decimals to fractions fluently
- Breaks apart multiplication problems strategically (34 × 6 = 30×6 + 4×6)
- Catches own errors by checking work
