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.4 – Solve one-step problems that involve addition and subtraction, using concrete objects and pictorial representations, and missing number problems such as 7 = ? - 9

  • 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.5 – Recognise and use the inverse relationship between addition and subtraction and use this to check calculations and solve missing number problems

          • 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.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 = _.

  • 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.
