Math Thinking Log
Over the last few days we have been talking about and using a Math Thinking Log. This is simply a log recording what and how we are thinking as we work through a problem. See our notes from today if you need a reminder.

The 2015-16 school year has begun. We have started our year working with divisibility rules for 2, 3, 4, 5, 6, 8, 9, &10 (and we through 7 in for good measure).

We have learned the following.
A number is divisible by 2 if ... the ones digit is even.
A number is divisible by 3 if ... the sum of the digits is divisible by 3.
A number is divisible by 4 if ... the last two digits are divisible by 4.
A number is divisible by 5 if ... the ones digit is 0 or 5.
A number is divisible by 6 if ... the ones digit is even and the number is divisible by 3 (see rule above)
A number is divisible by 8 if ... the number is even and if the sum of the last three digits is divisible by 9.
A number is divisible by 9 if ... the sum of the digits is divisible by 9.
A number is divisible by 10 if ... the last digit is 0.

NOTE: It is really important that students work on their multiplication facts. Everyone should know them by now but it wouldn't hurt to brush up on these facts.

PowerPoint: To create a new slid like the original, select New Slide and at the bottom there should be an option to Duplicate Select SlideWord: Copy the empty table (select ctrl c) then create a new page (Insert-> Break->New Page), paste table on new page (ctrl v)Budget/CostYou can use either the Word or Excel document, whichever you feel most comfortable with.

Everyone should know them by now but it wouldn't hurt to brush up on these facts.Next we will spend just a little time learning about and practicing factoring (Greatest Common Factor - GCM), prime numbers, and multiples (Lowest/Least Common Multiple - LCM).
