  • Place Value
  • Addition
  • Subtraction
  • Arithmetic


Add numbers by making tens. Break apart and combine numbers while focusing on place value. Use the adding screen to add any two numbers. Use the game screen to apply your make-a-ten strategies!

Sample Learning Goals

  • Improve understanding of place value by using different sizes of papers for ones, tens, and hundreds.
  • Develop mental math strategies when taking apart and putting together numbers.
  • Use the “make a ten” strategy when counting and doing addition.
  • Develop a mental model of the basic properties of numbers including commutativity, associativity, and closure.

This activity aligns with learning outcomes for Year 7 Solomon Islands Mathematics Curriculum:

Place Value:

  • 7.1.4 understand that our number system is “Base 10” and are made up of the following digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9 (u)
    • write and express numbers in figures using digits: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9, and also in words
  • 7.1.5 understand that a position of individual digits in a number holds different values and names (u)
    • identify the names and values of numbers in respect to the positions of the digits in the Place Value Table
    • arrange numbers in ascending and descending order according to their values.

  • Regarding to this as a new platform of learn capacity for our citizenship learners however but i would like to comment on my corner of confusion. wishes if the MEHRD to be uploaded all protocols and learning materials in PDF so that coverage of the system can reach out everywhere for learners and those who access to network and or internet.
    Today population getting increase in homes compare to education accessibility for people but only few. With that unfortunate ones can also in the same canoe too.

  • it is good all should be converted to pdf. which help students to get the notes to help them.
