COVID-19 Information

Dear High Tech High Families,

In a previous email we outlined HTH's plan for implementing distance learning in the event we did not reopen schools on April 7th.  San Diego Unified School District released a press release last night, indicating that they will not be returning on April 6th and will be implementing distance learning for all of their schools through the month of April.  We have officially decided that we follow suit and will not return for in person instruction on April 7th.

When HTH teachers return on April 6th, they will spend that week designing and piloting plans for distance learning.  We will be reaching out for your thoughts and feedback as we do this work.

We will roll out our approach to distance learning the week of April 13th and you will receive detailed information from your child’s teachers about what to expect going forward.  We are asking teachers to plan for their first distance learning module from April 13th - May 8th. Our hope is that by that time, we may be able to return to school, but if that is not the case, we will begin a second module that will run until the end of the year.

Leaders and teachers from across High Tech High have been working to design a framework for distance learning at our schools and create the infrastructure necessary to support that plan.  We’ll continue to engage in this work over spring break using your input regarding your technology access to help us craft an approach tailored to our community’s needs.

If your family currently does not have reliable internet access, please see the options that local internet companies are offering as families try to stay informed.  Getting Internet Access: Available Plans

Thank you for your patience and support. 




Estimadas HTH familias,

En un correo electrónico anterior, describimos el plan de HTH para implementar el aprendizaje a distancia en caso de que no volviéramos a abrir las escuelas el 7 de abril. El Distrito Escolar Unificado de San Diego lanzó un comunicado de prensa anoche, indicando que no regresarán el 6 de abril y que implementarán el aprendizaje a distancia para todas sus escuelas durante el mes de abril. Hemos decidido oficialmente que hacemos lo mismo y no volveremos para recibir instrucción en persona el 7 de abril.

Cuando los maestros de HTH regresan el 6 de abril, pasarán esa semana diseñando y poniendo a prueba planes para el aprendizaje a distancia. Nos pondremos en contacto para solicitar sus pensamientos y comentarios mientras hacemos este trabajo.

Implementaremos nuestro enfoque de la educación a distancia la semana del 13 de abril y su familia recibirá información detallada de los maestros de su hijo/a sobre qué esperar en el futuro. Estamos pidiendo a los maestros que planifiquen su primer módulo de aprendizaje a distancia para el 13 de abril al 8 de mayo. Nuestra esperanza es que para ese momento, podamos regresar a la escuela, pero si ese no es el caso, comenzaremos un segundo módulo que se ejecutará hasta el final del año escolar.

Los líderes y maestros de High Tech High han estado trabajando para diseñar un marco de referencia para el aprendizaje a distancia en nuestras escuelas y crear la infraestructura necesaria para apoyar ese plan. Continuaremos participando en este trabajo durante las vacaciones de primavera, utilizando su aportación con respecto a su acceso a la tecnología para ayudarnos a diseñar un enfoque adaptado a las necesidades de nuestra comunidad.

Inspiration for projects often comes when I least expect it. A radio article I heard on NPR about geocaching inspired me to create this math project. Immediately thoughts of longitudinal and latitudinal lines streaked across my mind creating a Cartesian plane.  Individual locations served as the coordinates; routes from one place to another were defined by linear equations.  A mathematical treasure map was born.

Initially, I imagined a traditional geocaching activity whereby students might use electronic GPS units to calculate latitude and longitude of specific locations, and from this data they could create linear equations which would define the line that intersects these points.  This idea was hampered by two main factors: the prohibitively expensive cost of supplying my class with decent quality GPS units and the logistics of supervising the hunt they would create. I scaled back the idea to fit the school and came up with the idea of creating a treasure hunt using the blue prints of the school. Students would be required to define ten stopping points within our school leading to the treasure. These points would be defined using a Cartesian coordinate system (X,Y) and connected using straight lines. It was not your typical treasure map, but the students were excited nonetheless.

My students had a solid understanding of integers and rational numbers, as well as the ability solve single step algebra equations, so I felt they were now ready to connect some dots… literally. This project was designed to teach, practice, and assess students’ knowledge of the Cartesian coordinate system, as well as their ability to create linear equations from lines and draw lines based on linear equations. To teach these skills, I projected a transparent grid onto a dry erase board, and we drew out imaginary treasure maps in classic pirate style on the white board. We discussed plotting points and the importance of having a common means for expressing location using the (x,y) coordinate system. We illustrated routes between two locations with a straight line, and we explored slope by comparing the steepness of lines for different routes. Students were able to practice what they learned by creating their own map, in which they needed to be able to write equations from the routes they drew as straight lines. The map they created would serve to assess their ability to translate lines to equations. Once they traded maps with another group, I could assess their ability to translate equations back to lines in order to create a route and eventually uncover the treasure.

In total, each group wrote ten equations to direct treasure hunters from one point to another.  Students chose the best method to write the equation for each line. Some used the line they drew to find the slope by tracing the rise and run with their finger, and then moved on to find the y-intercept by noticing where the line crossed the Y-axis. From there, it was as simple as plugging in the slope and y-intercept into the slope-intercept form for a linear equation, y = mx + b. Other groups chose to take a more algebraic approach, in which they used two points on the line to determine the slope, from the equation m = y2-y1/x2-x1 , and then used the point-slope formula, y – y1 – m (x – x1), to complete the equation. In order to express only a particular line segment that was their route, students bound the line using the domain and range. Once the linear equations, domains, and ranges for each route were found, students recorded the information onto the index cards that would become the clues for their treasure hunt.

One of the challenges that students encountered in crafting their maps was that not all lines crossed the y-axis in a place that was visible on the blueprint of the school. This initially frustrated some students, many of whom had really only paid attention to the slope-intercept approach for writing equations. I hadn’t planned on this complication, but it proved to be a great opportunity to introduce alternative methods for writing equations.  Students willingly engaged in the more labor intensive process of writing linear equations using the coordinates of two points because they wanted their maps to work.

Once their maps were drawn and their note cards complete, the hunt was on! Students traded in the role of map creators for the challenge of being treasure hunters. Each group set off on the hunt created by a group of their peers. They exchanged note cards with the first equation and raced to locate the initial stopping point on the treasure map.  A competitive spirit took hold as students rushed to translate the equation clue into a line, draw the line onto a photocopied map of the school, and then run to the first stopping point. If their calculations were correct, teams found a new note card at each stopping point with a new set of clues. After making their way through all ten equations and all ten stopping points, teams reached their treasure.

For a first time project, our mathematical treasure hunt was a great success! Students were motivated and engaged, they learned new algebraic concepts, and they gained a ton of practice in translating equations into graphs and vice versa without even realizing that what they were doing was work! However, once we moved into the hunt itself, I realized that I’d made an error in my planning. I’d been so excited to get the students into the hunt that I’d neglected to give the planning groups time to try out their own maps to check for accuracy.  As a result, they unwittingly passed off less than perfect clues, which resulted in hunting groups being unable to find their treasure.  Students quickly got frustrated and began to point fingers.  I thought I emphasized how important it was that their information be accurate; in retrospect,  I don’t think any amount of emphasis could have made this point more clear. What my students needed was to see for themselves how accurate– or inaccurate– their equations were. I’ll make sure to adjust the plan to allow for more practice next time.

Some students have a hard time engaging in math.
Efforts are made to make connections to the real world.
Sometimes the math we fit into the real world is forced into boring situations that students cannot relate to . . .
is it authentic for a child to be thinking about these complex adult world situations, that even adults dread thinking about?
I feel it can be equally, if not more valuable, to make connections to the make-believe world.
The world of play and imagination.
Play leads to engagement and real understanding. Why?
A meaningful challenge. A purpose for writing equations. A purpose for translating equations into lines.
A treasure. Who wouldn’t want to find it?
