So, here it is for Math activity Thursday--2nd Grade
To help understand that a two digit number consists of a group or groups of tens, plus the singles, my place value cards with oranges really comes in handy...
Although if you pick other objects to use like paperclips or cereal that's okay too. In second grade most children are learning about three digit places (typically ones, tens, and hundreds). I think it is a good idea for them to know typical money place value as well (hundredths, tenths, ones) so you would use pennies, dimes, and dollars.
One activity you can do with your students is to play a game called "What makes a Hundred"
Kids are in small groups--such as a math center.
A card is picked. (Let's say 43)
Use a 30 second timer and have them start it.
The students use white boards or paper to figure out how much they need to make a hundred. (43 + __ = 100)
After the 30 seconds are up everyone with the correct number gets a point.
They could play for a specific amount of time or play until someone gets 10 points (or some other predetermined number of points).
