Part B: Fill in the Blank
Write the correct answer on each line.
1. Sort food, toys, and clothes into three different groups.
Food, toys, and clothes are three kinds of items, so we sort into three groups.
2. Red, blue, and green make three color groups.
There are three color words listed, so they form three different color groups.
3. If 5 are circles and 1 is a square, the square is the odd one.
The square does not match the circles, so we call it the odd one out.
4. When sorting twice, first by color then by size, you use two rules.
Sorting first by color then by size uses two rules, which is multi-step sorting.
5. Counting each group helps us compare which group has more.
Counting each group lets us compare them to see which group has more items.
