Introduction to Tens and Ones ACMNA014 Count collections to 100 by partitioning numbers using place value (c) Professor Pete's Classroom, 2017. All rights reserved.

Assumed Prior Knowledge Students should already be able to: Read and write numbers to 20 Ability to count forwards and backwards to 100 starting at any number or point on the number line Prior experience bundling ten ones into a ten using bundling sticks and Unifix cubes (c) Professor Pete's Classroom, 2017.

Introducing Tens: Regular Names Talk about making groups of ten ones “ty” stands for “ten” note the similarity in sounds of “ty” and “teen” Start with the “regularly named” tens which include the single digit name: 60 70 80 90 seven eight eigh nine six tens ty 90 70 80 60

Introducing Tens: Forty When we say “forty” we hear the single digit name “four” The only irregularity is in the spelling: naughty forty lost its “u” four for tens ty 40

Irregular Tens: Twenty, Thirty & Fifty Lastly, introduce 50, 30 and 20” The first part does not name the number of tens: “twen” = 2 “thir” = 3 “fif” = 5 Note the similarities between: twenty & twelve thirty & thirteen fifty & fifteen five fif two twen three thir tens ty 20 30 50

Base Ten Materials 36 This resource includes “unbundling” activities for students to mirror with bundling sticks or Unifix cubes Base ten blocks should not be used here as they cannot be physically grouped or regrouped

The Value of Ungrouping Tens & Ones 52 Typically, place value activities involve showing numbers of tens and ones up to 9 Understanding that tens can be ungrouped to make individual ones is essential fifty-two ones

The Value of Ungrouping Tens & Ones A few “challenge activities” are included for use at the end of this Module, showing mixed tens and once in non-standard configurations Teacher discretion is needed as to whether students are ready for this stage 26 twenty-six

Accompanying Resources Lesson 2 and 3 Your choice of base ten materials can be used. Lesson 1, 2, 3 and 4 Print and duplicate as needed. Students can write in their books instead, if preferred. 240404_TBM105_T_Tens_Ones_boxes (c) Professor Pete's Classroom, 2017. All rights reserved.
