Classroom Geometry 6.G.A.1

Math Standard:

CCSS.Math.6.G.A.1- Find the area of right triangles, other triangles, special quadrilaterals, and polygons by composing into rectangles or decomposing into triangles and other shapes; apply these techniques in the context of solving real-world and mathematical problems.

Math Problem:

With this picture and standard I would have a worksheet for my students with a story on it. The story would include hints on things they would have to find in the classroom and solve the problem the story is asking. For example the students might have to find a right triangle in the classroom and figure out the two side lengths and then solve for the hypotenuse. I would have the students work together in teams to solve the different problems I would have set up around the room. Doing this shows the students how they use geometry in the real world. For example finding measures of the walls and solving for the area in a room. In real life you will need to know measurements of rooms when decorating, painting, building, etc. I also could have students use their tablets and the resources they have on them to solve the problems. Students can look up their own pictures and try and solve the angle measures in the pictures or they can use a tool to make shapes and solve for those shapes.

Language Arts Standard:

CCSS.LanguageArts.L.6.1- Demonstrate command of the conventions of standard English grammar and usage when writing or speaking.

Language Arts Problem:

I would incorporate this standard into this lesson because when talking in small groups and as a class I want my students to be speaking with the correct vocabulary from the lesson and use appropriate grammar. I would also have my students write a brief paragraph at the end of the lesson to see how they think they can use this in the real world. Having the students think of ways they can use it in everyday life shows the students that the lesson is not “pointless” and that “they will never use this again”.

How this lesson teaches culturally:

This lesson teaches culturally because the students will be using the tools that they learned to come together as a team or partnership to find thing around the room to solve. This is something that everyone can do at home or in the classroom. This also teaches culturally because I used student voice when I asked my students to write down how they would use this in the real world. Having students give their input and how they can use it in their life covers all areas of different cultures and lifestyles. The students are connecting it to their own life.

Fence Fractions – 4.NF.B.3

 

Students are engaged in real world application of mathematical modeling when creating a fence using fractions that have unlike common denominators to add to make a whole. Tommy is building a fence and has one side length finished (1 whole) and needs help finding the other sides to his fence. The students will be given different fractions to analyze on geogebra–an online tool for students to use to help conceptualize fractions with unlike denominators. This lesson is designed for a 4th grade class modeling addition of fractions.  Students will be working individually to help Tommy create his fence.
