Help Quizo the alien travel through space to find his home planet. Try rounding the distances to help find the estimated total distance he will travel on his route home. Next, we find farmer Wayne who is sharing out hay between his farm animals. Round the amounts of food each animal eats a day, to find out which animals farmer Wayne can feed. These challenges allow children to use the technique of rounding numbers to enable them to estimate answers. We have provided an example answer for each problem to guide you with your marking. Use this Year 4 Estimate Answers resource as a challenge activity or as a group activity with support.
