# 100 Numbers Group Task

"100 Numbers Group Activity" Sheets. **8 different number arrangements**. Free Printable 100 numbers sheets. Fun math activities for the first week of school. Beginning of the year group activity for math class. Number identification to 100.

## 1. Goal

Students will name features of good group work in a safe beginning of the year activity.

## 2. Task Description

This activity from Sara VanDerWerf is a keeper. Refer to her original blog post 100 Numbers to Get Students Talking, for details and additional ideas.

- Students work in groups of 3-5
- Each student has a highlighter
- Each group has one of the sheets
- Give the groups 2 minutes to find as many of the numbers from 1-100, consecutively, as possible
- At 2 min call "time" and have students put highlighters down.
- Group members will take turns going in a circle highlighting each number as they find it.
- Student 1 will highlight 1, student 2 highlights 2, student 3 highlights 3…. When we get back to student 1, they highlight the next number.
- They can help each other find numbers, but
**each student has to highlight their number** in turn.
- Students have usually found between 15-40 numbers.

- Have groups discuss strategy of how they found the numbers.
- Repeat the task with a new sheet of paper and 2 more minutes.
- Have students discuss again and then discuss as a class.
- Show patterns of sheets
- Do 3rd time. Usually one group gets to 100 during their 3rd try.
- Teacher task: During students working time, take photos of each group trying to attract the least attention.

- After the 3rd try, show the photos to students in your class working with their groups and ask then to list what a good group work looks like.
- Write a class list of features of quality group work.

## 3. Suggestions

- use this task the first week of school.
- This task is considered 'safe' by most. Students don't need to know one another to engage in the task. It requires little math knowledge.
- Follow up this task in the next couple of days with tasks with richer mathematics so students believe group work will be a norm in mathematics class.
