Describe the equal parts of shapes as halves, fourths, and quarters.Partition (divide) shapes like circles and rectangles into two and four equal pieces.Students who understand this principle can: three thirds, four fourths, etc.) They will also learn that the “equal shares of identical wholes” do not need to the same shape to equal each other (2.G.2-3).Ĭommon Core Standard: 1.GA.3 - Understanding Halves and Fourths They will also be able to cut shapes into equal parts and deepen their understanding of “part and whole relationship,” explaining that a whole can be made up of parts (i.e. Your students will learn to identify more complex shapes: triangles, quadrilaterals, hexagons and cubes (2.G.1). By understanding halves and fourths, your students will be able to work with, draw, and analyze shapes. This 1st grade skill of understanding halves and fourths will help your students when they move onto 2nd grade. They should also be familiar with making simple shapes to form larger shapes (K.G.6). squares, circles, triangles, etc.) and using formal and informal language to analyze and compare the shapes (K.G.1-3). Your students should be familiar with the Kindergarten skill of naming regular shapes (i.e. We then provide a breakdown of the specific steps in each video to help you teach your class. Below we show two videos that demonstrate how to identify halves and fourths. Understanding halves and fourths (or quarters) is a 1st grade Common Core math skill: 1.GA.3.
