What your child will practice
The workbook has 8 tip sheets, one for each big 3rd 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 and roundingEvery digit has a value that depends on its place. In 347, the 3 means 3 hundreds (300), the 4 means 4 tens (40) and the 7 means 7 ones.
- Tip 2: Adding and subtracting to 1,000Line up the ones, tens and hundreds. Start with the ones and work left. When a column makes 10 or more, carry 1 to the next column.
- Tip 3: Multiplying and dividingMultiplying is adding equal groups. Dividing splits a number into equal groups. They undo each other, so every × fact gives you two ÷ facts.
- Tip 4: FractionsA fraction is part of a whole cut into equal parts. The bottom number (denominator) says how many equal parts. The top number (numerator) says how many we count.
- Tip 5: Telling timeThe short hand shows the hour. The long hand shows the minutes: each number on the clock is 5 minutes, and each small mark is 1 minute.
- Tip 6: Area and perimeterArea is how many squares cover a shape. Perimeter is the distance all the way around it.
- Tip 7: Reading bar graphsA bar graph compares groups. The height of each bar shows how many. Always read the scale first: the lines may count by 2s, 5s or 10s.
- Tip 8: Solving word problemsRead the story twice. Find the question. Decide what to do, solve it, then check that the answer makes sense.
