Yesterday the second graders acted as teachers. They taught the first graders how to use book creator. It was great to see the students working so well together! Today we took advantage of the gorgeous weather and brought our geometry lesson outside. Today we learned that area is the measure of space inside a shape. Today we worked with the triangle and quadrilateral cards we created yesterday. We learned that an you can differentiate triangles by the lengths of their sides. An isosceles triangle has two sides the same length, a scalene triangle has no sides of equal length, and an equilateral triangle as all sides the same length. Today the Vermont Institute of Natural Science (VINS) presented on raptors. We learned that a Raptor, or bird of prey, is characterized by:
We learned many cool facts and also got to see a Red Tail Hawk, American Kestrel Falcon, and a Barred Owl. We have begun our geometry unit. On Monday students took a pre-test (these will be sent home soon, I just need to record the scores) and learned a new workplace game called: Last Shape in Wins. This is a strategy game that involves placing different polygons on a game board. On Tuesday we read The Greedy Triangle which introduced us to many different polygons. We learned that a triangle has 3 sides and angles, a quadrilateral has 4 sides and 4 angles, a pentagon has 5 sides and 5 angles, and so on (all the way up to an octagon!). We then used the geoboards to practice making different triangles. Not all triangles look the same! On Thursday we will learn the terms for different types of triangles (Isosceles, Equilateral, Scalene, and right). Today we used the geoboards to make different quadrilaterals. A quadrilateral is a polygon with 4 sides and 4 angles. And just like with triangles, not all polygons look the same! There are trapezoids, rhombuses, squares, rectangles, etc.! |
