Geometry Lesson

The students created 3-dimensional shapes from 2-dimensional paper. We used an activity from Exploratorium called Cut-Fold-Staple. I modeled the template and first round of cutting with the students. We made predictions about what the shape would look like when it was unfolded. From the student responses I could discern that most of the students could conceptualize what the shape would look like unfolded. It was more challenging for them to choose their own shape to create. There were lots of tiny shapes and a few without a straight edge.  I introduced the concept of rotational symmetry and reflections.



The students then used Educreations to label the line of symmetry on their shape. I was excited to see one of the quietest students share her labeled photo with the whole group. She often declines to work on group projects or share her ideas so it was a big step to speak in front of others.

Ollies and Math

Thanks to generosity of Chevron through Donors Choose , my math class experienced a new mobile technology, Ollies! Ollies are programmable robots made by  Sphero . We used the app,  Macrolab  to program the Ollies. I modified a lesson from the Sphero website to teach the concepts of measurement and data. The first day, we explored how to program the Ollies and how changing the variables in the program affected what Ollie did. The students recorded data to capture what they were seeing. On day 2 it was time to be more methodical with our data collection. Students only changed one variable at a time. This allowed students to discover the relationship between time and the distance that the Ollie traveled. The students changed the variable of the delay between the roll and stop commands to develop this understanding. There was definitely a lot of excitement and motivation to learn measurement. On Day 3, we analyzed the data recorded from each group. There were some noticeable differences

Roller Coasters

The students chose words to describe roller coasters. We recorded them using  Answer Garden . I think it also describes what building roller coasters is like. There was a buzz of excitement as groups of students designed and constructed marble roller coasters. One of the student remarked, "This doesn't look like regular library time." He had just asked me if he could tape the roller coaster ramp to the wall and was shocked when I said, "Of course." The students were so engaged with their projects that they did not notice a visitor from the  Hillsboro Tribune . Kathy Fuller came to learn about what was happening in our building this summer. We are proud that we will be featured in the newspaper. I will make sure to include the link in a future post. We will be continuing our roller coaster construction tomorrow. I am very thankful that our custodial staff is supportive of these messy projects. This video captures the feelings expressed in the wordl

Halfway

I am taking it as a positive sign that we are halfway through our summer program and there is still tons of positive energy. Mrs. Gonzalez and Ms. Ayala's phone calls resulted in 5 new students today! We are expecting even more new students on Monday. My hope is that we can bring the average daily attendance to 40 students. This article affirmed our purpose for the summer program and pushing the students to work on their math skills in addition to reading. http://www.vox.com/2014/7/13/5891583/summer-slide-achievement-gap-vacation I am looking forward to comparing their end of the year MobyMax math placement with their beginning of the year placement test score. Plans for next week... Model canoes, gardening, writing a Scratch character description and an art project
