3MG.1.0:

Students choose and use appropriate units and measurement tools to quantify the properties of objects.

 

hmtoggle_plus13MG.1.1 Choose the appropriate tools and units (metric and U.S.) and estimate and measure the length, liquid volume, and weight/mass of given objects.

 

 

hmtoggle_plus13MG.1.2 Estimate or determine the area and volume of solid figures by covering them with squares or by counting the number of cubes that would fill them.

 

 

hmtoggle_plus13MG.1.3 Find the perimeter of a polygon with integer sides.

 

 

hmtoggle_plus13MG.1.4 Carry out simple unit conversions within a system of measurement (e.g., centimeters and meters, hours and minutes).

 

 

 

 

3MG.2.0:

Students describe and compare the attributes of plane and solid geometric figures and use their understanding to show relationships and solve problems.

 

hmtoggle_plus13MG.2.1 Identify, describe, and classify polygons (including pentagons, hexagons, and octagons).

 

 

hmtoggle_plus13MG.2.2 Identify attributes of triangles (e.g., two equal sides for the isosceles triangle, three equal sides for the equilateral triangle, right angle for the right triangle).

 

 

hmtoggle_plus13MG.2.3 Identify attributes of quadrilaterals (e.g., parallel sides for the parallelogram, right angles for the rectangle, equal sides and right angles for the square).

 

 

hmtoggle_plus13MG.2.4 Identify right angles in geometric figures or in appropriate objects and determine whether other angles are greater or less than a right angle.

 

 

hmtoggle_plus13MG.2.5 Identify, describe, and classify common three-dimensional geometric objects (e.g., cube, rectangular solid, sphere, prism, pyramid, cone, cylinder).
