In math class we are studying Geometry. We did an activity where we sorted shapes. We sorted the shapes into categories like 3D shapes, 2D shapes and by their sizes. We learned some shapes are called perpendicular shapes. We know there are 3 types of angels. A right angle is exactly 90 degrees, an acute angle is below 90 degrees, and an obtuse angle is greater than 90 degrees. We were learning about tangrams. We watched a short video to learn how to cut out and make tangram shapes. We discovered we could make animals and boats. Similar shapes are ones that look the same but one is smaller than the other. Congruent shapes are exactly the same size and shape. Some lines are parallel because they keep on going and never stop and do not cross. We are starting to make shapes into snowflakes. We are going to look at symmetry.
Our class is wondering about somethings:
Is there something called 100D?
Are there any more shapes or angles?
What is a 30 degree, 14 degree, 10 degree angle?
Is there such things as a 1 degree angle?
Is there such thing as a negative dimension (-D) shape?
Please comment on our blog with your answers!
Thank you,
