I recently wrote for the CUE Blog on how to own a premade curriculum. I spoke about taking it and tweaking it so that we, as teachers, feel the ownership instead of feeling like we have no say. Part of the way I take ownership in my math class is to use Andrew Stadel‘s Estimation 180 site. It’s a nice warm-up for the students and a great way to practice several of the 8 Mathematical Practices found in CCSS.
Most recently, we have been going through a series that has us estimate the value of coins in a container. It started with pennies, then progressed through until the day we estimated the value of dimes. We went through our normal routine – three minutes to discuss and find an estimate that is too low, too high, the actual estimate, and how they arrived at that estimate. Then, as normal, we viewed the video answer. Upon finding the answer, the RSP co-teacher got a discussion started. She disagreed with the answer. We left it at that so that the students could either agree or disagree. After they reviewed the previous two days’ answers and compared the answer to the dimes, the class determined that they too disagreed. Following the Mathematical Practices, they had to justify their reasoning, which they did. They reasoned that the pennies and nickels were mounding up to the point of almost spilling over, whereas the dimes didn’t quite reach the top of the container – same container.
Fortunately, with modern technology, we didn’t have to let the discussion die there. So, I got on my phone, hooked it up to the screen so the students could be active participants, jumped on Twitter, and sent Mr. Stadel a private message. This is what they wrote, well, told me to type:
After they got over the initial shock that one could actually do this, they got excited. Now, I have only been a participant in a few of Mr. Stadel’s sessions at conferences but was fairly certain that he would be open to what we had to say and would most likely respond. And he didn’t disappoint! The kids were VERY excited that he did respond. Okay, I was pretty excited too. This was such a real and relevant experience.
We then talked about how many more dimes we thought could fit. They determined that 1/2 roll more – 25 dimes – would be needed.
THIS is why we, as educators, need to be connected. THIS is why we continuously grow our PLN.
I would like to thank Mr. Stadel and Ms. Luke (RSP teacher) for making this all possible.
I got pretty excited about this. THIS makes their learning even more relevant. They now have a chance to talk with another class somewhere in the US. I encouraged my students to answer questions and check out what the other students had written. Some were silly (a string of letters) and my students were disturbed by this. Which I took as a compliment. This means they know what I expect from them and that that sort of Internet activity isn’t acceptable. My students then began answering questions and reading the information.
trivia and location skills. Players are given a trivia question, which correlates to a place in the world, that they then must place Peg Man on the map. This game was developed by Google. The closer you are to the location, and faster you are, the more ‘miles’ you earn. You are given 1000 miles to start the game. However, if you are not accurate you lose ‘miles’. So if your answer is 149 miles away, that’s how many ‘miles’ or points you lose. Once you are out of ‘miles’ the games ends.
This is a super fun, highly addictive game (if you’re a nerd like me!). There are 2 modes and several GeoGuessr Maps to choose from. When you arrive on the site, the first game is ‘Explore the World’. Using Google Maps Street View, you are dropped in a location. Using clues (signs, vegetation, cars, etc.) you need to place a pin on the map as to the location of where you are. Scrolling a bit further down on the page, there are several maps focusing on countries, cities, and continents. I clicked on ‘North America’ where game maps for Canada and United States, along with some cities, appeared. You can set a timer for minutes and seconds. I mentioned a second mode: Challenge. This is where you can challenge a friend.
One of the bigger shifts in math, aside from the building blocks in the CCSS Framework, is the ever dreaded ‘Explain your answer’. When this first came out, I wasn’t sure what they meant, the frameworks hadn’t been written yet. I had students explaining that they ‘added the ones then regrouped to get the answer.’ And while they were technically correct, there was a lot missing.
