• Counting to 100 by ones and tens •Counting forward from a given number other than 1 •Can write numbers 0-20 •Can represent a number of objects with a written number 0-20 •Shows one-to-one correspondence when counting •Understands that the last number counted tells the number of objects counted •Counts to answer, "How many?" •Can count objects in a line, array, or scattered configuration •Can identify whether a number of objects in one group is greater, less than, or equal to the number of objects in another group •Compares numbers
•Can represent addition and subtraction with fingers, manipulatives, drawings, and equations •Can solve addition and subtraction word problems within ten •Can decompose numbers within ten in more than one way (ex. 5=2+3, 5=0+5, 5=1+4) •Can tell different ways to make ten, given any number 0-9 •Fluently adds and subtracts facts within five
•Can compose and decompose numbers from 11 to 19 into ten ones and some further ones •Can represent teen numbers by using objects or drawings •Understands that teen numbers are composed of one group of ten and some ones.
Measurement and Data
•Can describe measurable attributes of objects, such as length, weight, capacity, area •Can describe several measurable attributes of a single object (ex. length and weight) •Compares two objects with the same measurable attribute to tell which is more/less •Can classify objects into given categories •Can count the numbers of objects in each category •Can sort the categories by count
•Describes objects in the environment using names of shapes •Describes the relative positions of these objects using position words (ex. above, below...) •Correctly names the shape, regardless of size or orientation •Identifies two-dimensional shapes by name (circle, square, rectangle, triangle, hexagon) •Identifies three-dimensional shapes by name (sphere, cone, cylinder, cube) •Can identify two-dimensional shapes as "flat" and three-dimensional shapes as "solid" •Compares two- and three-dimensional shapes (ex. the number of sides, corners, length of sides...) •Models shapes by building with sticks or drawing •Can compose simple shapes to form larger shapes (ex. Can you form a rectangle using these 2 squares?)
