Pick a level and answer real questions right here. Every question is made fresh, so there is always another one, and a wrong answer shows how to solve it step by step. These are the same questions Kiwi Tutor gives kids in their own practice.
Levels 4 to 10 come with the family plan.
Roughly 4th and 5th grade. Level 1 is adding tenths and level 10 is multi-step word problems with money.
Decimals are fractions with 10 or 100 on the bottom: 0.3 is 3/10 and 0.25 is 25/100. Kids who see that connection make fewer place-value mistakes. In the Common Core standards most US schools follow, decimals start in 4th grade and adding, subtracting, multiplying and dividing them to hundredths comes in 5th.
To add or subtract, line up the decimal points first, then work like whole numbers. To multiply, ignore the points, multiply, then count the decimal places in both numbers to place the point in the answer. Money problems are good practice because kids already have a feel for $1.50 + $0.75.
In a Kiwi Tutor account, each kid gets their own Decimals level, set by a short placement quiz. A few right answers in a row and the next questions get a little harder; a couple of misses and they ease back. Wrong answers come with the same step-by-step explanation you see here, missed topics come back until they stick, and a parent can see each kid's accuracy by topic.
Decimals is part of the family plan ($10/mo): all 10 levels, adaptive for each kid, plus every other subject for up to 5 kids. Addition, Subtraction, Multiplication and Division stay free for up to 2 kids. Compare the plans ->
