Telling Time
1. Stating the problems.
I will answer four problems from your worksheet: question 6 (read a clock), question 7 (how to say times), question 8 (place value in 540), and question 9 (use a doubles fact for 7 + 8).
2. Formula and important rules.
To read minutes on an analog clock, multiply the minute-hand number by $5$ to get minutes past the hour.
Each numeral on the clock represents $5$ minutes.
When the minute hand points to $6$ that is half past because $6\times 5=30$ minutes.
The place-value rule: a digit in the hundreds place represents the digit times $100$.
A doubles strategy: use a known fact like $n+n$ and adjust by $1$ when adding $n+(n+1)$.
3. Solution for question 6.
Read the clock: the minute hand on the $8$ means $8\times 5=40$ minutes past the hour.
If the hour hand is slightly before $5$, the time is $4:40$.
Among the multiple-choice options listed (20 minutes past 11, 25 minutes past 11, half past 11), none match a clock that reads $4:40$.
Therefore the correct time for the described clock is $4:40$.
4. How to say the time (fill the blanks).
Use the phrase "$m$ minutes after $h$" to say $h:$mm when minutes are not $30$.
Examples corresponding to the three choice formats are:
$20$ minutes after $11$.
$25$ minutes after $11$.
half past $11$ which means $11:30$.
5. Solution for question 8 (place value).
In the number $540$ the digit $5$ is in the hundreds place, so its value is $5\times 100 = 500$.
Therefore the value of the digit $5$ is $500$.
6. Solution for question 9 (doubles fact and sum).
We want $7+8$.
Use the doubles fact $7+7=14$ and then add $1$ to get $7+8 = 7+7+1 = 14+1 = 15$.
Doubles fact: $7+7=14$.
So $7+8=15$.
7. Final answers.
Q6: $4:40$ (none of the listed 11:20, 11:25, 11:30 choices match).
Q7: fills: "$20$ minutes after $11$", "$25$ minutes after $11$", half past $11$.
Q8: $500$.
Q9: doubles fact $7+7=14$ and sum $15$.
