Solving Addition and Subtraction Word Problems- Check!

This week the class prepared for an end of the unit assessment of rounding, place value, and solving addition and subtraction problems.  Those word problems can be very tricky when you are trying to figure out which operation to use.  Today we worked in groups to underline key information in the problems written by 3-Langenmayr.

 Then, we found the numbers that represented parts or wholes for our formula P + P = W.  The group then sorted the problems into the two groups: addition or subtraction. Next, we solved the problems on our own in our notebook.

 

The last step was to check our answers using the ScanQR Chrome app.

This was a quick and easy way to check our work!

A Little Help from My Friend Google

We have been hard at work researching the seven continents using the book Explore Earth's Seven Continents.  After receiving "text-dependent" questions through Google Classroom, we set off to read and answer.   Some of the questions had some unknown words and the class learned a new trick. Instead of asking a teacher, students learned to use the Tools in Google Docs.
First we highlighted the word we wanted to define and clicked on "Tools"...

Then we clicked on "Define"...

And on the side a Research window popped up with the definition!

Maybe Google can correct and grade our documents too...

Ah but it can!
