‘Geometry is the branch of mathematics that addresses spatial sense and geometric reasoning.’ (Howse & Howse, 2014). It is one of the basic mathematical concepts they cover in almost, if not all, the formal educational years they go through before year 2, which are the kindergarten years and year 1. Most of the children are indirectly exposed to different shapes from the beginning of their lives when becoming in contact with different objects, and therefore, when it comes to learning of the different shapes, it might help the children to get a better grasp of it.
The previous basic knowledge about geometrical shapes might be beneficial for the children to grasp new facts about the shapes which are included in the year 2 syllabus. The year

Therefore, it is crucial for the practitioner to handle and present the topic to the children with appropriate activities so that the children would be able to become knowledgeable about the subject. Van Hiele talks about five levels for the Development of Geometry, two of which until the children are in year two they would have covered. ‘The basis of the theory is the idea that a student’s growth in geometry takes place in terms of distinguishable levels of thinking.’ (Howse and Howse, …show more content…
In this activity, the children will be split into groups, according to the number of students, and pre-cut shapes will be hid around the class from before. The children will then be asked to look out for different shapes while setting a timer on the interactive whiteboard. When the time is out, the children will be then asked to stay in groups and identify and sort the shapes by gathering them according to the shape. Then, as a group they count example how many circles they gathered and jot them down on a blank paper, so when the teacher asks them to give out their records they will be able to answer.
This activity should help the children as it is spot on in what is exactly expected from them in the level 0 of Van Hiele’s theory and also the curriculum. Another activity would be taking the children on an outing to spot different types of shapes in an outside setting. The children will be invited to bring a clipboard and try to spot different shapes in which objects are in, and draw them. This will help them understand and recognize shapes in many different settings even when they are not in the
counting them, and shape by moulding different shapes out of it. It also helps children
The streetlamp outside paints shapes across the wall next to my bed. I can see them in the darkness, dull orange lines that have become familiar in my many restless nights. At the heart of their canvas, they intersect to form a rectangle. A rectangle? For months I believed in this reality of form with the inborn certainty that accompanies that which is obvious. I didn’t have to think about it. Nightly, I would study the shape in a sleep haze, unconsciously harboring knowledge of its regularity. Except that it is not a rectangle.
While the studies at Governor’s School are noticeably more advanced and require more effort than at regular public schools, I see this rigor as the key to my academic success. For me, the classes I take that constantly introduce new thoughts that test my capability to “think outside the box”, are the ones that capture all my attention and interest. For example, while working with the Sierpinski Triangle at the Johns Hopkins Center for Talented Youth geometry camp, I was struck with a strong determination to figure out the secret to the pattern. According to the Oxford Dictionary, the Sierpinski Triangle is “a fractal based on a triangle with four equal triangles inscribed in it. The central triangle is removed and each of the other three treated as the original was, and so on, creating an infinite regression in a finite space.” By constructing a table with the number black and white triangles in each figure, I realized that it was easier to see the relations between the numbers. At Governor’s School, I expect to be provided with stimulating concepts in order to challenge my exceptional thinking.
According to Roland Shearer (1992) the release of non-Euclidean geometries at the end of the 19th Century copied the announcement of art movements occurring at that time, which included Cubism, Constructivism, Orphism, De Stijl, Futurism, Suprematism and Kinetic art. Most of the artists who were involved in these beginnings of Modern art were directly working with the new ideas from non-Euclidean geometry or were at least exposed to it – artists such as Picasso, Braque, Malevich, Mondrian and Duchamp. To explain human-created geometries (Euclidean, non-Euclidean), it is a representation of human-made objects and technology (Shearer
I assume the point of teaching this skill was to help apply it to real life situations, but sadly, triangles simply aren't the same thing as world
An example of the difference in the abstract geometry and the measurement geometry is the sum of the measures of the angles of a trigon. The sum of the measures of the angles of a trigon is 180 degrees in Euclidian geometry, less than 180 in hyperbolic, and more than 180 in elliptic geometry. The area of a trigon in hyperbolic geometry is proportional to the excess of its angle sum over 180 degrees. In Euclidean geometry all trigons have an angle sum of 180 without respect to its area. Which means similar trigons with different areas can exist in Euclidean geometry. It is not possible in hyperbolic or elliptic geometry. In two-dimensional geometries, lines that are perpendicular to the same given line are parallel in abstract geometry, are neither parallel nor intersecting in hyperbolic geometry, and intersect at the pole of the given line in elliptic geometry. The appearance of the lines as straight or curved depends on the postulates for the space.
One of the children (George) created a map, that did not look like a physical representation of the children outdoor area, when his partner asked what he was drawing he explained he was using his imagination. The ‘water represents the big children’s playground, our area is the island, the dotted line is where we have to find the word treasure, that’s hidden under the X!’ George’s partner Pedro looked puzzled and asked me why he was doing it wrong. I explained that George was not doing it wrong, it is his interpretation of his outdoor area, and this is how he imagines it. This allowed me to be reflexive and flexible as a researcher, and to ensure at all times the child’s voice was being heard, and that I was not shaping the research to the outcome I wanted. I also thought this was a lovely example of children’s imagination. The child’s outdoor area can represent a number of things to them as expressed through George map. As adults we will never think how children do, or how we once did (Christensen, 2004). Child lead learning and child participation is increasingly being valued, as reflected in the literature. The map-making activity was a superb way to extend the pupils critical thinking, contributing to their communication and language development. Examples from my observation reflect the impact the
Areas of the following shapes were investigated: square, rectangle, kite, parallelogram, equilateral triangle, scalene triangle, isosceles triangle, right-angled triangle, rhombus, pentagon, hexagon, heptagon and octagon. Results The results of the analysis are shown in Table 1 and Fig 1. Table 1 showing the areas for the different shapes formed by using the

This assignment will distinguish the relationships between teaching practice, children’s mathematical development and errors and misconceptions. Hansen explains how “children construct their own knowledge and understanding, and we should not see mathematics as something that is taught but rather something that is learnt” (A, Hansen, 2005). Therefore, how does learning relate to errors and misconceptions in the class room, can they be minimised and is it desirable to plan lessons that avoid/hide them? Research within this subject area has highlighted specific related topics of interest such as, the use of dialogue in the classroom, the unique child and various relevant theories which will be discussed in more depth. The purpose of this

It involves language, mental imagery, thinking, reasoning, problem solving, and memory development. Jean Piaget stages of cognitive development are the sensorimotor period (birth to 2 years). Children at the sensorimotor stage becomes more goal-directed oriented with goal moving from concrete to abstract (Driscoll et al., 2005). Children at the preoperational period (2-7), engage in symbolic play and games, but has a difficult time seeing another person’s point of view (Driscoll et al., 2005). For example, teaching a preoperational child can provide opportunities to play with clay, water, or sand. Children at the concrete operational period (7-11), solves concrete problems in a logical fashion (Driscoll et al., 2005). For example, providing materials such as mind twisters, brain teasers, and riddles. The formal operational period (11-adulthood) is when student’s solve abstract problems and develop concerns for social issues (Driscoll et al., 2005). For example, making sure that tests that’s given has essay questions and asks a student to come up with other ways to answer the
When I was in high school, I was very involved in the arts. I took a band, choir and two years of visual art. During the years of high school, I knew that the fees for the art courses cost much more than other electives at my school. I also observed that the school focused more on their athletic and academics programs, than on their art programs. We had many fundraisers to raise more money for the art programs even after paying an already expensive fee to takes these electives. Schools are neglecting the visual arts programs and placing all of their money and focus on academics and athletics programs. I propose a balance between the arts, academics, and the athletics.
