##### Learning Objective:

Use bead strings to model numbers in different ways

##### Intended Outcome:

Students ‘trust’ the count and can explain their thinking, i.e. they do not need to count all the beads to represent the number

##### Materials and How to make the bead strings:
• For the cord use a bead string or a shoe lace for easy threading
• Choose two colours (bead strings of many different colours can confuse children)
• Place groups of 5 or 10 beads together before changing colours – this helps children to count the beads
• Tie a loop in the end for easy storage or display
##### Instructions:
• Each student holds their bead string in front of them
• Teacher names a number, for example, “Show me 7”
• Students use their bead strings to model the number
• Teacher asks students to explain how they know they are showing that number
• Student replies, “I know 5 and 2 makes 7”
• Teacher prompts students to show the number another way
##### Whole Class Activity: I wish I had…*
• Students stand in a circle with their bead string
• Teacher begins with a statement like, “I have 10 beads”
• All students show 10 beads on their string
• Teacher now says, “I wish I had 9” – all students change their bead stings to show the new number
• The next student in the circle continues the game “I have 9 beads, I wish I had 12”
• All students model the new number
• This process of identifying and changing the number of beads continues
• A discussion about the various methods students use to make and move between the different numbers can take place during and after the activity
