WALT divide a 2-digit number by a 1-digit number. 

 Starter:

Today we are going to divide 2-digit numbers by a 1-digit number by partitioning.  We need to remember how to partition a number into tens and ones. 

Can you partition the following numbers into 10s and 1s:  18, 23, 58, 68

18 = 10 and 8                  23 = 20 and 3          58 = 50 and 8                68 = 60 and 8

Today we are going to divide 2-digit numbers by a 1-digit number by partitioning into tens and ones and then sharing into equal groups.  How can we partition the number?  How many tens are there?  How manuy ones are there?  What could we use to represent this number?  How many equal groups do I need?  How many rows will my place value chart have?  How does this link to the number I am dividing by?  These are just some of the questions you need to ask yourself. 

There are 2 ways we could represent our calculations:  Have a look. 

Did you have a go at the calculations using each method? 

How did you do?  Any problems please message me on Dojo so we can address them.  We are going to be moving on tomorrow.
