All Lessons

(A) Count forward and backward to at least 20 with and without objects

(F) Connect number names, numerals and quantities, including zero, initially up to 10 and then beyond (ACMNA002)

K.CC.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).

K.CC.4.C Understand that each successive number name refers to a quantity that is one larger.

K.CC.3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).

K.CC.7 Compare two numbers between 1 and 10 presented as written numerals.

(F) Generate a number that is one more than or one less than another number up to at least 20

(F) Establish understanding of the language and processes of counting by naming numbers in sequences, initially to and from 20, moving from any starting point (ACMNA001)

K.CC.2 Count forward beginning from a given number within the known sequence (instead of having to begin at 1).

(C) Count a set of objects up to at least 20 and demonstrate that the last number said tells the number of objects in the set regardless of their arrangement or order

(F) Subitise small collections of objects (ACMNA003)

K.CC.4.B Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted.

L.K.1.F Produce and expand complete sentences in shared language activities.

L.K.1.B Use frequently occurring nouns and verbs.

L.K.1.B Use frequently occurring nouns and verbs.

(B) Read, write, and represent whole numbers from 0 to at least 20 with and without objects or pictures

(F) Connect number names, numerals and quantities, including zero, initially up to 10 and then beyond (ACMNA002)

K.CC.3 Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects).

(A) Model the action of joining to represent addition and the action of separating to represent subtraction

K.OA.1 Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

(D) Apply basic fact strategies to add and subtract within 20, including making 10 and decomposing a number leading to a 10

(Y1) Represent and solve simple addition and subtraction problems using a range of strategies including counting on, partitioning and rearranging parts (ACMNA015)

K.OA.5 Fluently add and subtract within 5.

2.OA.2 Fluently add and subtract within 20 using mental strategies. By end of Grade 2, know from memory all sums of two one-digit numbers.
