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.! A line plot shows how frequently something occurs by displaying data on a number line. Today we practiced plotting data on a line plot. We gathered the data by conducting a simple experiment. We built a boat out of tinfoil and then counted how many pennies our boats held. We have been learning:
We have looked at and practiced making tally charts, bar graphs, and pictographs. With a pictograph it's important to have a key! We have collected data from our second grade class, but quickly realized 11 kids makes for a small sample size! So we have also collected data from other classes. Today the students went “grocery shopping.” They had $10 to spend on one protein, one vegetable, one fruit, one snack, and one drink. The player with the most money remaining after grocery shopping won. “Money disappears quick when you’re spending it!” I heard one student say. So true! 😉 |
