All Lessons

(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.

(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.

(I) Compose and decompose numbers up to 10 with objects and pictures.

(Y1) Count collections to 100 by partitioning numbers using place value (ACMNA014)

K.NBT.1 Compose and decompose numbers from 11 to 19 into ten ones and some further ones, e.g., by using objects or drawings, and record each composition or decomposition by a drawing or equation (such as 18 = 10 + 8); understand that these numbers are composed of ten ones and one, two, three, four, five, six, seven, eight, or nine ones.

(A) Give an example of a measurable attribute of a given object, including length, capacity, and weight

(B) Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

K.MD.2 Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

(B) Compare two objects with a common measurable attribute to see which object has more of/less of the attribute and describe the difference.

(F) Use direct and indirect comparisons to decide which is longer, heavier or holds more, and explain reasoning in everyday language (ACMMG006)

K.MD.2 Directly compare two objects with a measurable attribute in common, to see which object has "more of"/"less of" the attribute, and describe the difference. For example, directly compare the heights of two children and describe one child as taller/shorter.

(E) Classify and sort a variety of regular and irregular two- and three-dimensional figures regardless of orientation or size

(F) Sort and classify familiar objects and explain the basis for these classifications. Copy, continue and create patterns with objects and drawings (ACMNA005)

K.MD.3 Classify objects into given categories; count the numbers of objects in each category and sort the categories by count.
