Part of the Year 2 statistics chapter. Chapter overview · whole chapter on one page
Simple tables
A table puts counts in rows and columns. It is easy to read.
Find the name in the first column. Then read the number in the same row.
A total is all the numbers added together.
Key ideas
- Read along a row to find the number.
- The total is all the counts added together.
- Use the total to find a number that is hidden.
- The biggest number is the most.
Method. Find the row for reading. Then read the number in that row.
- Find the row for reading. The row for reading is in the table.reading
- Read the number in the right-hand column. That number is how many chose it.reading: 9
- Write the answer. 9
Check. Read the same row again. The number is still 9. ✓
Watch out. Read along the row to its number. Do not read the number from the row above or below.
Method. Find each count, then add them all together.
- Write down each count. Each count is one row.drawing 4, reading 9, baking 6
- Add the counts together. Add them all, so none is missed.4 + 9 + 6 = 19
- Write the answer. 19
Check. Add them in the other order to check: 6 + 9 + 4 = 19. ✓
Watch out. Make sure every row is in your total, and no row is counted twice.
Method. Compare the counts. The biggest count is the most.
- Write down each count. Put each count next to its name.drawing 4, reading 9, baking 6
- Find the biggest count. 9 is the biggest count.biggest: 9
- Write the answer. The reading row has 9.reading
Check. Every other count is smaller than 9. ✓
Watch out. Check every count, not only the first two. The most is the count that is bigger than all the others.
Watch out
Watch out: read the number in the same row as the name. Do not read the row above or below.
Exam tip
Grown-up tip. Make a small table of toys or snacks on paper, with a count in each row. Ask: “How many in this row? Which row is the biggest? What is the total?”
Exercise 10E Simple tables
Non-calculatorMethod. Find the row for cycling. Then read the number in that row.
- Find the row for cycling. The row for cycling is in the table.cycling
- Read the number in the right-hand column. That number is how many chose it.cycling: 9
- Write the answer. 9
Check. Read the same row again. The number is still 9. ✓
Watch out. Read along the row to its number. Do not read the number from the row above or below.
Method. Find the row for kites. Then read the number in that row.
- Find the row for kites. The row for kites is in the table.kites
- Read the number in the right-hand column. That number is how many chose it.kites: 4
- Write the answer. 4
Check. Read the same row again. The number is still 4. ✓
Watch out. Read along the row to its number. Do not read the number from the row above or below.
Method. Find the row for ball games. Then read the number in that row.
- Find the row for ball games. The row for ball games is in the table.ball games
- Read the number in the right-hand column. That number is how many chose it.ball games: 6
- Write the answer. 6
Check. Read the same row again. The number is still 6. ✓
Watch out. Read along the row to its number. Do not read the number from the row above or below.
Method. Find the row for running. Then read the number in that row.
- Find the row for running. The row for running is in the table.running
- Read the number in the right-hand column. That number is how many chose it.running: 7
- Write the answer. 7
Check. Read the same row again. The number is still 7. ✓
Watch out. Read along the row to its number. Do not read the number from the row above or below.
Method. Compare the counts. The biggest count is the most.
- Write down each count. Put each count next to its name.ball games 6, cycling 9, kites 4, running 7
- Find the biggest count. 9 is the biggest count.biggest: 9
- Write the answer. The cycling row has 9.cycling
Check. Every other count is smaller than 9. ✓
Watch out. Check every count, not only the first two. The most is the count that is bigger than all the others.
Method. Compare the counts. The smallest count is the fewest.
- Write down each count. Put each count next to its name.ball games 6, cycling 9, kites 4, running 7
- Find the smallest count. 4 is the smallest count.smallest: 4
- Write the answer. The kites row has 4.kites
Check. Every other count is bigger than 4. ✓
Watch out. Check every count, not only the first two. The fewest is the count that is smaller than all the others.
Method. Find each count, then add them all together.
- Write down each count. Each count is one row.ball games 6, cycling 9, kites 4, running 7
- Add the counts together. Add them all, so none is missed.6 + 9 + 4 + 7 = 26
- Write the answer. 26
Check. Add them in the other order to check: 7 + 4 + 9 + 6 = 26. ✓
Watch out. Make sure every row is in your total, and no row is counted twice.
Method. Find each count. Then take the smaller count away from the bigger one.
- Count the cycling. There are 9.cycling: 9
- Count the ball games. There are 6.ball games: 6
- Take the smaller count away from the bigger one. The difference is how many more or fewer.9 - 6 = 3
- Write the answer. 3
Check. Add the difference back on: 6 + 3 = 9. ✓
Watch out. Take away the smaller number from the bigger one. Do not add them.
Method. Add the counts you can see. Then take the sum away from the total.
- Add the counts you can see. These counts are shown in the table.6 + 4 + 7 = 17
- Take the sum away from the total of 26. The hidden count for cycling is what is left.26 - 17 = 9
- Write the answer. 9
Check. Add the hidden count back on: 17 + 9 = 26. ✓
Watch out. Use the total to find the hidden number. Do not guess it from the picture.
Method. Find each count, then put the rows in order of their counts, most first.
- Write down each count. Put each count next to its name.ball games 6, cycling 9, kites 4, running 7
- Put the counts in order, most first. Start from the biggest count.9 → 7 → 6 → 4
- Write the order. cycling, running, ball games, kites
Check. Check that each count is smaller than the one before it. ✓
Watch out. Compare the counts, not the names. The longest name does not mean the biggest count.
Method. Add up each side of the claim, then compare the two totals.
- Add the counts for running. They make 7 altogether.7 = 7
- Add the counts for ball games and kites. They make 10 altogether.6 + 4 = 10
- Compare the two totals. 7 is fewer than 10.No
Check. The claim compares running with ball games and kites. It is not right. ✓
Watch out. Add the counts on each side first. Then compare the totals, not the single rows.
