Stacks On! is a hands-on counting and number recognition activity designed for early learners. Students use counters or Unifix blocks to stack the correct number of objects on each numeral, reinforcing their ability to subitise, count, and match numbers in a fun and engaging way. This resource helps build one-to-one correspondence, early numeracy skills, and fine motor development.
Name, represent and order numbers including zero to at least 20, using physical and virtual materials and numerals
Recognise and name the number of objects within a collection up to 5 using subitising
Quantify and compare collections to at least 20 using counting and explain or demonstrate reasoning
Recognise, represent and order numbers to at least 120 using physical and virtual materials, numerals, number lines and charts
Partition one- and two-digit numbers in different ways using physical and virtual materials, including partitioning two-digit numbers into tens and ones
Quantify sets of objects, to at least 120, by partitioning collections into equal groups using number knowledge and skip counting
Subitise small collections of objects
Compare, order and make correspondences between collections, initially to 20, and explain reasoning
Recognise, model, read, write and order numbers to at least 100. Locate these numbers on a number line
Count collections to 100 by partitioning numbers using place value
Establish understanding of the language and processes of counting by naming numbers in sequences, initially to and from 20, moving from any starting point
Develop confidence with number sequences to and from 100 by ones from any starting point. Skip count by twos, fives and tens starting from zero
Describes mathematical situations using everyday language, actions, materials and informal recordings
Uses objects, actions, technology and/or trial and error to explore mathematical problems
Uses concrete materials and/or pictorial representations to support conclusions
Counts to 30, and orders, reads and represents numbers in the range 0 to 20
Uses a range of mental strategies and concrete materials for multiplication and division
Applies place value, informally, to count, order, read and represent two- and three-digit numbers
Supports conclusions by explaining or demonstrating how answers were obtained
Uses objects, diagrams and technology to explore mathematical problems
Describes mathematical situations and methods using everyday and some mathematical language, actions, materials, diagrams and symbols
Reads numerals and represents whole numbers to at least 20
Uses the structure of equal groups to solve multiplication problems, and shares or groups to solve division problems
Reasons about representations of whole numbers to 1000, partitioning numbers to use and record quantity values
Demonstrates an understanding of how whole numbers indicate quantity
Reasons about number relations to model addition and subtraction by combining and separating, and comparing collections
Applies an understanding of place value and the role of zero to read, write and order two- and three-digit numbers
Subitise small collections of objects
Recognise, model, read, write and order numbers to at least 100. Locate these numbers on a number line
Compare, order and make correspondences between collections, initially to 20, and explain reasoning
Count collections to 100 by partitioning numbers using place value
Establish understanding of the language and processes of counting by naming numbers in sequences, initially to and from 20, moving from any starting point
Develop confidence with number sequences to and from 100 by ones from any starting point. Skip count by twos, fives and tens starting from zero
• Print in A3 size for a larger interactive experience.
• Provide a laminated version for repeated classroom use.
• Use different coloured counters or blocks to represent various numbers and patterns.
• Have students predict and check the total before stacking.
• Challenge students to add two stacks together to introduce basic addition.
• Use dice to roll a number and stack the corresponding amount.
