2.GM.1Identify, describe, and draw two-dimensional shapes. Shapes include: triangles, regular pentagons, regular hexagons, and quadrilaterals (square, rectangle, trapezoid, parallelogram, rhombus)2.GM.10Describe relationships of time. Times include: seconds in a minute; minutes in an hour; hours in a day; days in a week; and days, weeks, and months in a year2.GM.11Solve real-world problems involving addition and subtraction of time intervals in half hours or hours.2.GM.12Count collections of mixed coins and solve real-world problems involving quarters, dimes, nickels, and pennies within 99¢ and whole dollar amounts.2.GM.2Identify and describe three-dimensional shapes based on the shape, number of faces, number of edges, and number of vertices. Shapes include: rectangular prisms, cubes, and square-based pyramids2.GM.3Select appropriate measurement tools to estimate and measure the length of an object to the nearest whole inch or whole centimeters.2.GM.4Demonstrate how the length of an object does not change, regardless of the units used to measure it, by measuring the length of an object twice; use two different length units, describing how the two measurements relate to the size of the chosen unit.2.GM.5Measure to determine how much longer or shorter one object is than another, expressing the length difference in terms of a standard length whole unit.2.GM.6Solve real-world problems involving lengths of the same units, using addition and subtraction within 100.2.GM.7Solve real-world and mathematical problems to find the perimeter of polygons.2.GM.8Partition a rectangle into rows and columns of same-size squares, counting the total number of squares to find the area.2.GM.9Using an analog clock, tell and write time to the nearest five minutes using colon notation and indicate a.m. or p.m.
