Data Handling

Data Handling in IB PYP Grade 1 Mathematics

Data handling is about collecting information and showing it clearly. In the PYP Data Handling strand, Grade 1 learners sort objects, count and record with tally marks, and read simple picture graphs and bar charts to answer questions such as “Which has the most?”

PYP learning is inquiry-based, so every worksheet here is short, colourful and playful, with a friendly animal guide and a teacher answer key on page 2.

What learners practise

Sorting objects by colour, shape or kind
Making tally marks and counting them in fives
Reading picture graphs and using a key
Reading bar charts and finding most and least
Answering “how many more?” questions from data

Data at a glance

Tally marks: four lines and a slash make 5
Picture graph: each picture stands for one (or two)
Bar chart: the taller the bar, the greater the number
Most / least: look for the tallest or shortest bar

For students

Read each instruction carefully, try every question and colour the animal when you finish.

For parents

Print on A4, read the instructions aloud together and let your child work alone before you check.

For teachers

Use a worksheet as a starter, homework or exit ticket. Each one has a name, class and date box and an answer key.

Teaching tip

Collect real data in class, such as favourite fruits, and make a tally together. Then turn it into a picture graph and a bar chart.

Quick answers

Who is the Data Handling page for?

It is for IB PYP Grade 1 Mathematics learners, typically aged 6–7, and for the parents and teachers who support them.

What data skills do Grade 1 learners need?

Sorting, tallying, reading picture graphs and simple bar charts, and answering questions about most, least and how many more.

Is a picture graph the same as a pictograph?

Yes. Both show data using pictures; each picture can stand for one or for more than one item, as shown in the key.

How should I use these worksheets?

Pick one worksheet, let your child try it without help first, then check together with the answer key on page 2. Short sessions of five to ten minutes, a few times a week, work best.
