What? More Subtraction?

Yes! 


How lucky are you???


Today we are going to use that 100s chart again to think about subtraction as skip counting backwards. Since we are working on place value, we are going to focus on 10s. 

Here you have a video with a short explanation, don't you love her accent?



Now do page 2 of the math problems from last time. 


Don't forget,  do page 2

To solve the problems also use the splat 100s chart and make a splat each time you count back by 10. Or you can print out this 100s chart and color it in the old fashioned way.





And let's finish up with a fun game subtracting 10s from 100. If the cheering is distracting, you can always mute your device. But who doesn't love people cheering for them now and then?
