1st Grade Magnitude Math Lessons

Hi! It's Sarah from Learning is for Superstars! I hope you had a great Christmas and a wonderful break! It's been hard getting back into the swing of things ... packing lunches, using an alarm clock, getting to bed early, getting up early, homework ... But here we are!

My first graders are learning about estimation when looking at a group of objects and then decide if there are 3, 30, or 300. Or perhaps there are 7, 70, or 700 M&Ms in the bag. Or perhaps 2, 20, or 200 pencils in the box. 
About how many snowmen are there?
about 4
about 40
about 400
About how many butterflies are there?
about 1
about 10
about 100

We started by using this Smart Board activity I found on Smart Exchange. Do you know of Smart Exchange?? If not, it's free to join! Download Smart Board activities to use in your classroom. I love it!

Anyway ... here's a glimpse into the activity, along with the link.
Then they are to explain their reasoning. My favorite story is a little boy who said he could watch movies for 20 hours ... until a classmate looked at him and said "All day?!" Yep, they understand it now!

We finished up our first lesson with sorting these candy pictures by 2, 20, or 200. We made category headings in our math notebook and then the children cut, sorted, and glued them down under the headings. Click on the image to download your own!
We worked on making logical guesses on how many using these clip cards.
 The children saw the bags of candy we were going to use in the math bin and I didn't talk at all about them until Wednesday. It was funny to watch them glance towards it during two days of lessons!
Then I pulled them out with a recording page for them to choose about how many there are in each bag.
These are in my magnitude pack. Click on the images or here to find it on TpT!

Jen, another Virginia teacher from An Adventure in Literacy, has created this fabulous Reasonable Magnitude unit, which I am using this week. Check out this great product on teaching magnitude!

This is a challenging unit to find resources on, so I hope that Jen and I have been able to help you out! See you back in February!
