Does homework actually help primary school children?
The research is mixed: homework seems to help primary-school children a little, mostly with specific skills like arithmetic, but the boost to overall achievement is much smaller and less consistent than for older students.
Some meta-analyses find modest benefits, others find the evidence for elementary-age academic gains is weak, and no Canadian body has issued specific guidance on this question.
Mixed
Findings come from meta-analyses and systematic reviews of observational and quasi-experimental studies, not randomized trials isolating homework's causal effect, and different reviews reach different conclusions for primary-age children.
What the evidence says
There's no simple yes-or-no answer here. A well-known synthesis of homework research covering 1987-2003 found that homework was linked to better test scores in high school and, to a lesser extent, middle school, but the evidence for an academic benefit in elementary school was described as only faint. More recent reviews are a bit more optimistic: one systematic review looking at children from roughly grade 2 through grade 8 concluded homework does help, particularly with arithmetic and problem-solving skills, though it couldn't pin down how much homework is ideal.
A separate meta-analysis on 'e-homework' (digital assignments) found a positive but modest overall effect, with elementary students benefiting less than high schoolers. Putting these together, the honest picture is: homework for primary-age kids probably has some positive relationship with skills like math practice, but it isn't a strong or guaranteed academic booster the way it can be for teenagers, and quality (short, purposeful, well-matched to the child) seems to matter more than quantity. We couldn't find a Canadian Paediatric Society, Health Canada, or other Canadian guideline that directly weighs in on whether homework helps primary-school children academically.
The closest Canadian statement we found discusses managing screen use during homework time, not whether homework itself is worthwhile, so on this specific question Canadian-specific guidance is currently absent.
