Math workshop

Math workshop has been full of new activities based around place value, base 10 and reviewing fact families.  Students love the independent activities, the partner games and the small group teacher instruction.   How can you extend this learning at home?  Ask you child to write random numbers 0-100, ask them to represent that number in tens and ones, ask them to write the expanded notation of that number, you can extend it further by asking them to add a ten to that number and what number do they have now and how do they know, minus 10 to the original number and what number do they have now and how do they know.

Example: 
Parent:  Write 54
Kid:  l l l l l . . . . (they count 10, 20, 30, 40, 50, 51, 52, 53, 54)
Parent:  Can you write the expanded notation equation to represent those tens and ones?
Kid:  50+4=54
Extention:
Parent:  What number would you have if you added one more group of ten 
Kid: (the process to figure this out will look a variety of ways)
Parent:  How do you know?
Kid: Explains their work
Parent:  Can you write the equation to match?
