Decimals, Estimation & Negative Numbers Bundle

By the end of these seven lessons your child can read, compare and calculate with decimals, round to decimal places and to significant figures, estimate an answer before working it out, and handle negative numbers in all four operations. Money, measures, percentages and algebra all sit on top of these skills, so a gap here comes back in every one of them.

What's included:

• Understanding, Comparing and Ordering Decimals - 7 units (Numbers Between Whole Numbers, Tenths, Hundredths and Thousandths, Equivalent Decimals, Comparing Two Decimals, Ordering Decimals, Decimals With Whole Numbers), 104 questions
• Rounding Decimals to Decimal Places - 6 units (To 1 Decimal Place, To 2 Decimal Places, To 3 Decimal Places, Trailing Zeros and Padding, Rounding That Carries, Mixed and Reasoning), 102 questions
• Significant Figures and Estimation - 7 units (The First Significant Figure, Rounding to 1 Significant Figure, Rounding to 2 and 3 Significant Figures, Zeros and Traps, Estimating With 1 Significant Figure, Dividing By a Number Less Than 1, Overestimate and Underestimate), 104 questions
• Multiplying and Dividing by Powers of 10 - 7 units (Multiply Whole Numbers, Divide Whole Numbers, Multiply Decimals, Divide Decimals, One Number Changes, Both Numbers Change, Using the Inverse), 104 questions
• Adding and Subtracting Decimals - 6 units (Adding Tenths and Hundredths, Adding Thousandths and Ten Thousandths, Subtracting Tenths and Hundredths, Subtracting Thousandths and Ten Thousandths, Choosing the Quickest Method, Decimals in Real Life), 104 questions
• Multiplying and Dividing Decimals - 5 units (Counting Decimal Places, Multiplying Decimals, Dividing By a Whole Number, Dividing By a Decimal, Decimals in Context), 114 questions
• Negative Numbers - 5 units (Numbers Below Zero, Adding and Subtracting a Positive, Adding and Subtracting a Negative, Multiplying and Dividing, Mixed and Order of Operations), 90 questions

Your child works through each lesson on any screen. They play with the tool at the start of a unit, click to reveal each line of a worked example, set the practice questions out on paper, then click to check their own answer.

How it's structured:

• Each of the 43 units opens with a worked example your child clicks through one line at a time, then practice questions graded from easy up to the hardest thing that unit asks for
• 722 questions in total across the 7 lessons, every one with a click-to-reveal answer and a reveal-all option, and most question banks have a New Questions button that deals a fresh set whenever you want more
• Every lesson closes with its own mixed challenge pulling from all its units, including spot-the-mistake, true or false with a reason, and two-step word problems

22 hands-on tools a printed worksheet cannot give you. A place value slider that moves every digit a column at a time, so ×10 stops being "add a zero". A zoomable number line that opens up the gap between 4.6 and 4.7 until the thousandths are visible. A decider digit table that shows exactly which digit decides the rounding and which ones never matter. A column builder that lines the points up and reveals one column per click. A fact chain machine that takes 3 × 4 = 12 and shows what happens to the answer when one number moves, then when both move. A number line that crosses zero so subtracting a negative stops being a rule to memorise.

Use this if:

• Your child is in Year 4 to Year 11 and decimals still feel like a different kind of number to them
• You are preparing for the 11+ or GCSE Foundation, where estimation, significant figures and negatives are guaranteed marks
• Your child lines the digits up instead of the decimal points, writes 0.7 as smaller than 0.65, or gets lost the moment two minus signs meet
• You want a resource your child can check their own work with, not one more thing on your to-do list

Who this is for

Built for students who want to practise independently, at their own pace, with clear examples and instant feedback rather than a static worksheet.
