CIRCLES AND TRIANGLES AND SQUARES, OH MY!
When I first saw that geometry was a common core standard starting in 1st grade, I immediately thought of the geometry I took sophomore year of high school and panicked...not my strongest subject. Obviously, I quickly realized they meant basic shapes and was relieved- then I did some digging...there's no way they're just learning to recognize a triangle in the 2nd grade, right? Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes. Partition a rectangle into rows and columns of same-size squares and count to find the total number of them. Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.
