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

          • KS1.Y1.N.AS.3 – Add and subtract one-digit and two-digit numbers to 20, including 0

  • KS1.Y2 – KS1 Year 2
    • Year 2 programme of study
      • KS1.Y2.N.AS – Number - addition and subtraction

        • Pupils should be taught to:

          • KS1.Y2.N.AS.3 – Add and subtract numbers using concrete objects, pictorial representations, and mentally, including:

  • Year 2
    • Number and Algebra
      • Number and place value

        • ACMNA029 – Explore the connection between addition and subtraction

  • 3 – Year 3
    • 3.NA – Number and algebra
      • 3.NA.3 – Continue spatial patterns and number patterns based on simple addition or subtraction.

  • 4 – Year 4
    • 4.NA – Number and algebra
      • 4.NA.3 – Create and continue spatial patterns and number patterns based on repeated addition or subtraction.

      • 4.NA.1 – Apply basic addition and subtraction facts, simple multiplication facts, and knowledge of place value and symmetry to:

        • 4.NA.1.a – Combine or partition whole numbers

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

        • K.OA.2 – Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

  • 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.6 – Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

      • 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 = _.

  • 2 – Grade 2
    • 2.OA – Operations & Algebraic Thinking
      • Mathematics

        • 2.OA.2 – Fluently add and subtract within 20 using mental strategies. (See standard 1.OA.6 for a list of mental strategies.) By end of Grade 2, know from memory all sums of two one-digit numbers.
