The sentence that demonstrates correct subject-verb agreement is:
The children visited their grandparents last weekend.
This sentence uses the past tense "visited" appropriately with the plural subject "children."
The other sentences either misuse the tense in relation to time ("last weekend" indicates a past action) or are repetitions.
