Hello Math Department!
This week we will be blogging about Double Bubble Maps. Double Bubble Maps are used to compare and contrast two ideas/themes. In Double Bubble Maps students can use more than just adjectives to describe ideas, they can now use any word of phrase in the maps. I am curious to see how you adapt this to a math lesson. Y'all did a wonderful job using the bubble maps. I have been very impressed with y'alls thinking maps thus far.
Happy Blogging!

I used the double bubble map in comparing the solving procedures for equations and inequalities. I liked this map - it plainly showed the differences and the similarities of solving between the 2 procedures.
ReplyDeleteI had a hard time trying to find something to use this week for double bouble maps. Mainly because I was in the middle of units for all my classes. Maps I find are easier to introduce a topic with.
ReplyDeleteI ended up doing one with my geometry group comparing and contrasting polygons & circles. At first, all they notice is that they are two different things. They realized you find perimeter with polygons, but circles you find circumferance. Then they realized polygons & circles have a similarity - you can find area for both. I felt like it was a stretch to use double bouble this way. But my classes did well with it.
I created a double bubble map comparing the standard form of a quadratic equation to the vertex form. Students tend to look at the different forms as seperate animals. The double bubble map helped to link these two forms together.
ReplyDeleteI used a double bubble map with my fast track classes comparing solving systems of equations by graphing and elimination. They could easily identify the differences but had a hard time with similarities. Once I helped them with the similarities, they got the picture.
ReplyDeleteWell...I had planned on using a double bubble map this week in Pre-Cal, but ran out of time due to the assembly on Wednesday. I will, however, implement it at the beginning of next week. We are currently studying transformations of graphs. My plan is to allow my students to compare and contrast vertical stretches/compressions with horizontal stretches/compressions. I am going to allow my students to work in groups to complete the map and then come together as a class to discuss their findings.
DeleteKeep up the blogging!!!!!
ReplyDeleteWe created a double bubble map to compare and contrast Standard form and Vertex form of quadratic functions. The use of this map shows the students that the a value of both forms are the same. It also shows the students how to get the vertex for both forms and how to identify the translations from the parent function.
ReplyDeleteI used the double bubble map with fast track for system of equations. I used the word graphing and substitution. They were able to tell me that they both would give you an order pair for the answer, but they couldn't come up with anymore things they had in common until I helped them. They did a good job giving me different things. It was a way I reviewed for the quiz.
ReplyDeleteI also did a double bubble with solving systems but with my Math Tech 2 class. I was quite impressed how fast they came up with the similarities. They responded well to this method/ thinking map, so I think I will use it in the future to help with comparing and contrasting related topics.
ReplyDeleteI used the double bubble map to compare and contrast Similarity and Congruence with my Geometry students. I think it helped them see that there are more comparisons between these two concepts than they tend to think. It actually helped them understand that congruent figures are actually similar to each other with a 1:1 ratio. Mission complete.
