This will not only introduce elementary students to geometry, but also begin the complicated thinking associated with algebraic concepts. Using the formula to plug in the known degrees and then find the x is the beginning of much more abstract algebraic thinking.

Circles rule our lives and have rules of their own! Each circle measures to 350 degrees, and with this knowledge we can begin to find unknown angles!
If a circle measures 360, that means that a half circle measures half -- 180 degrees. In a half circle, there are many different angle combinations. But, we know that they all equal out to 180 degrees.
Knowing this, we can find the great unknown!
Well, we know that the total of the two angles equals 180 degrees. Therefore, angle 1 = angle 2 = 180 degrees.
Let's just plug the numbers into the equation.
63 + x = 180.
The first step is to isolate the variable, in this case the x. We do this by getting rid of the 63 on the left side...
Unfortunately, the traditional textbook-based skills approach focuses on memorizing by rote measurement facts (e.g., equivalent measures such as 12 inches = 1 foot) and measurement procedures (e.g., how to use a ruler)" (1998, p. 15-9). Absent hands-on exercises, though, many young learners will not have an opportunity to construct an understanding of the process of measurement or a concept of measurement unit which can frequently result in mechanical and inappropriate
Mathematics InstructionIntroductionArt can play an important role in the teaching of math to young learners by providing visual and hands-on experiences that can enhance understanding and engagement. Using art in math instruction can help students make connections between mathematical concepts and real-world applications, which can make math more meaningful and relevant to them. One way art can be used in math instruction is through the use of manipulatives (D�angelo &
Another important strategy is that of exploring spatial relations. In such activities, children gain a better visual and practical sense of the spatial relations within mathematics. Scholastic's article portrays two girls discussing the appropriate spatial placement of a couch in a dollhouse. Such thinking methods can be influenced utilizing activities asking the children to map their house, their school, or their neighborhood in proportions. This will help open the
