Tens and Ones Place Value Tool: MAB Builder (Foundation to Year 2)

MAB Builder: Tens and Ones is a place value tool for Foundation to Year 2 by Teach This, an interactive PowerPoint tool aligned to the Australian Curriculum. Students represent and partition two-digit numbers into tens and ones using virtual MAB blocks. Each tap on the Tens or Ones button adds one block, and the number at the top and the value under each column update straight away. There are three modes: Build a number, Guess my number and Make my number. Make my number gives 10 numbers to build, such as 14, 40 and 96, with a yellow cover that reveals each answer. It opens in Microsoft PowerPoint on any interactive whiteboard, panel or projector, with no macros, no student logins and no student data collected.

Model a number during explicit teaching, then switch to Guess my number while students write the hidden number on mini whiteboards. It saves sorting tubs of physical MAB for a whole-class demonstration.

Learning goals

  • We are learning to read, write and order numbers to 20 using concrete materials, connecting quantities, numerals and number names.
  • We are learning to read, write, name and order two-digit numbers to at least 120 using concrete materials, hundred charts and number lines.
  • We are learning to show that one- and two-digit numbers can be partitioned in different ways, such as partitioning two-digit numbers into tens and ones.
  • We are learning to show that two- and three-digit numbers can be partitioned and re-named in different ways, such as partitioning three-digit numbers into hundreds, tens and ones.
  • We are learning to count forwards and backwards up to 20.
  • We are learning to compare and order numbers to 20 using words such as ‘more’, ‘less’, ‘same’ or ‘first’, ‘second’, ‘third’.
  • We are learning to read, write, model and represent numbers to 100 in different ways and on number lines.
  • We are learning to count collections to 100 using place value groupings.
  • We are learning to count collections to 1000 using place value groupings.

MA1-4NA old Applies place value, informally, to count, order, read and represent two- and three-digit numbers MA1-3WM old Supports conclusions by explaining or demonstrating how answers were obtained MA1-2WM old Uses objects, diagrams and technology to explore mathematical problems MAe-1WM old Describes mathematical situations using everyday language, actions, materials and informal recordings MAe-2WM old Uses objects, actions, technology and/or trial and error to explore mathematical problems MAe-3WM old Uses concrete materials and/or pictorial representations to support conclusions MAe-4NA old Counts to 30, and orders, reads and represents numbers in the range 0 to 20 MA1-1WM old Describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols MAE-RWN-02 new Reads numerals and represents whole numbers to at least 20 MA1-RWN-01 new Applies an understanding of place value and the role of zero to read, write and order two- and three-digit numbers MA1-RWN-02 new Reasons about representations of whole numbers to 1000, partitioning numbers to use and record quantity values
VCMNA087 Recognise, model, read, write and order numbers to at least 100. Locate these numbers on a number line VCMNA072 Compare, order and make correspondences between collections, initially to 20, and explain reasoning VCMNA069 Establish understanding of the language and processes of counting by naming numbers in sequences, initially to and from 20, moving from any starting point VCMNA088 Count collections to 100 by partitioning numbers using place value VCMNA105 Group, partition and rearrange collections up to 1000 in hundreds, tens and ones to facilitate more efficient counting

Differentiation

Modifications

Start with Build a number and teen numbers only, and have students count the ones blocks aloud before adding a ten. Pair the tool with real MAB blocks on desks so students can copy each build.

Extensions

Ask students to build a number, then say what it would become with one more ten or one less ten before tapping the blocks to check.
