Dave Hewitt
In the first video, I liked Dave's idea of using the entire classroom as a learning tool. His introduction to algebra and number line lesson was also taught by allowing students to speak in unison. This gave every student an opportunity to reflect on their learning. This made me stop and reflect on my role as a teacher candidate. However, as I was watching the video, I felt like the lesson was dragged on for too long. For example, I would implement more activities and foster group collaboration after a quick interactive lesson. Otherwise, if my lessons are too long, I believe my students will lose focus and interest. Another stop that was interesting was the concept of powers of the mind that was mentioned in the second video. He mentioned that there are different powers of the mind; one of them being memory. As teachers, we need to make sure that memory isn't the only skill that is being taught to the students. This is so common, especially in a mathematics classroom. It was also interesting to learn that we can learn a lot from little. His example of fractions made sense. We need a common name to add fractions and this can be easily explained with the concept of addition. I was able to learn that educating awareness is necessary instead of making students memorize information. I think Hewitt created the fraction problems to support awareness. This problem helped me understand how fractions work and that fractions can be equivalent even when they don't have the same denominator. These examples are crucial for students as they are able to build awareness in them. It will allow them to apply their knowledge instead of using their memory to solve it. Hence, I will need to be definitely thoughtful of the examples I give to my students in my teaching.

The Giant Soup Can of Hornby Island
We need 1291 liters of water to control a fire, hence there is enough water to put out an average house fire because the water tank can hold around 17,861 L of water.
This problem allows students to use proportions, estimating, and reasoning. Students may get stuck when they need to find the dimensions of the actual Campbell Soup can and the height of the bike in the photo. They also might get stuck figuring out the diameter of the tank from the height of the bike just by looking at the picture. However, this is a good problem as it allows them to connect to the real world. The problem is realistic and practical. Being able to estimate is a crucial skill because we use it all the time in our daily lives when we go to the grocery store. Further, allowing students to find the information they need to solve word problems is also an important skill that is needed when they become adults.
One way I would extend the problem is by allowing students to look at the length of the bike in the photo instead of the height. In this case, they would need to figure out how high the tank is when given the length of the bike. This will help them realize that they only need one dimension of the bike to solve the problem when they are given the dimensions of a normal-sized soup can.

Here is another extension problem. About one person can fit in between two hedges. What would be the total area of the six hedges at the front not including the hedges at the back. This will allow students to estimate the width and length of the hedges using their knowledge of human measurements. Further, they will need to consider the gap between the hedges when calculating the area.
