A spider has eight legs. Which model shows how many legs three spiders have?
We can model the question using a number line. Each spider has eight legs, so we need to count forward in eights. There are three spiders, so we need to model three jumps of eight on the number line. This represents one spider. This represents two spiders. Two eights are 16. And this represents three spiders. Three eights are 24. This model shows how many legs three spiders have.
