Testimonials

What a brilliant site you have!!! I love it, especially as it saves me hours and hours of hard work. Others who haven't found your site yet don't know what they are missing!

It is quite frankly the best money I have ever spent on my child. I really cannot thank you enough for providing this, it really is brilliant.

You have the most amazing program. Everybody loves it and the student's results have been in the high 90%'s, it's definitely due to your program.

  • KS1.Y1 – KS1 Year 1
    • Year 1 programme of study
      • KS1.Y1.N.AS – Number - addition and subtraction

        • Pupils should be taught to:

          • KS1.Y1.N.AS.2 – Represent and use number bonds and related subtraction facts within 20

  • Year 1
    • Number and Algebra
      • Number and place value

        • ACMNA015 – Represent and solve simple addition and subtraction problems using a range of strategies including counting on, partitioning and rearranging parts

  • 2 – Year 2
    • 2.NA – Number and algebra
      • 2.NA.1 – Apply counting-on, counting-back, skip-counting, and simple grouping strategies to combine or partition whole numbers

      • 2.NA.3 – Create and continue sequential patterns by identifying the unit of repeat

      • 2.NA.4 – Continue number patterns based on ones, twos, fives, and tens.

  • K – Kindergarten
    • K.OA – Operations & Algebraic Thinking
      • Mathematics

        • K.OA.1 – Represent addition and subtraction with objects, fingers, mental images, drawings (Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.)), sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

  • 1 – Grade 1
    • 1.OA – Operations & Algebraic Thinking
      • Mathematics

        • 1.OA.1 – Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem. (See Glossary, Table 1. http://www.corestandards.org/the-standards/mathematics/glossary/glossary/ )

      • Mathematics

        • 1.OA.3 – Apply properties of operations as strategies to add and subtract. (Students need not use formal terms for these properties.) Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

      • Mathematics

        • 1.OA.8 – Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ – 3, 6 + 6 = _.
