Chapter Overview
Always read the title, labels, and picture key before answering a pictograph question.
Data Handling teaches children to sort information, count items, use tally marks, and read simple pictographs. Data helps answer questions such as which item is most popular or how many objects are in each group.
Sorting and Tallying
- Sort objects by one clear feature such as colour, shape, or size.
- A tally mark records one item.
- Count each object once and place it in the correct group.
- Compare groups using most, least, more, fewer, and equal.
Reading a Pictograph
- A pictograph uses pictures or symbols to show data.
- The label tells what each row represents.
- The key tells how many items each picture represents.
- Count the pictures in a row, then use the key to find the value.
