Problem Solving - Sharing our learning

We had so much fun sharing our solutions on our Apple TV, using draw free, a cool i-pad app.

Problem

A group of students is standing in a circle. Every student faces someone across the circle. The students count off in order, starting with the number 1. Student 2 stands across from student 7. How many students are in the circle?

Yaisa explained her thinking.

Practice investigation - Complete this with a partner or by yourself.

1.      Question (What are you wondering about?)

          What is the favourite fruit of room 4’s students?

2.      Collect your data/information using a tally chart

Types of fruit	Tally	Frequency

3.      Present your information/data with a bar graph. Add the labels 
to explain your graph. Then show the same data in your workbook, 
using as many different graphs as you can.
