A handy mental strategy to try!

Hi everyone!

Take a look at our new Mental Math multiplication strategy, "Noticing Nines."
Ex: 7 x 99
Yikes! That sounds hard! 😟
Don't worry! It's actually easier than you might think!
We can round up 99 to 100, making the question 7 x 100.
7 x 100 = 700.
In rounding, we included 1 too many groups of 7 in our answer, so we have to balance
our answer by subtracting 7. 700 - 7 = 693.
So, 7 x 99 = 693. Ta da!

This strategy is extremely helpful when dealing with money, too!
Four loaves of bread at $1.99? No problem!
1. 4 x $1.99 = $?.??
2. 4 x $2.00 =  $8.00
3. $8.00 - $0.04 = $7.96
4. 4 x $1.99 = $7.96

Please, try this one at home! :)
