In grade 1, students will know, with accuracy and speed, the addition and subtraction facts for whole numbers with sums to 20. Using a variety of strategies, they will explore multi-digit addition and subtraction to mentally calculate to 100 and to solve everyday problems. They will develop an understanding of how addition and subtraction are related. First grade students will extend their understanding of the place value system, i.e. knowing that the placement of numerals determines the value of a number up to the hundreds place. Students will measure time to the hour and half hour. They will continue their study of measurement to understand that items are measured by using equal units of measurement. The study of geometric shapes, both plane and solid, will continue to build understanding of the attributes of shapes and combination of shapes to make new shapes. This will develop the initial understanding of congruence and symmetry.
