What your child will practice
The workbook has 8 tip sheets, one for each big 4th grade topic. Every question on the daily pages shows the number of the tip sheet that explains it, so your child always knows where to look.
- Tip 1: Place value to 1,000,000Each place is worth 10 times the place to its right. In 352,618 the 3 means 300,000, the 5 means 50,000 and the 2 means 2,000. The comma separates the thousands.
- Tip 2: Adding and subtracting big numbersLine up the places, start with the ones and work left. Carry when a column makes 10 or more. Borrow when the top digit is too small.
- Tip 3: Multiplying and dividingBreak big numbers into tens and ones, multiply each part, then add. To divide, share out the biggest place first.
- Tip 4: FractionsEqual fractions name the same amount. Multiply (or divide) the top and bottom by the same number to find one.
- Tip 5: DecimalsDecimals are another way to write tenths and hundredths. The first place after the point is tenths; the second is hundredths.
- Tip 6: Measurement, area and perimeterTo change a bigger unit into a smaller one, multiply by how many small units fit in one big unit.
- Tip 7: Angles, factors and primesA right angle is 90°. A straight line is 180°. Factors are numbers that multiply together to make a number.
- Tip 8: Solving word problemsRead the story twice, find the question, decide what to do, solve, then check that the answer makes sense.
