In one sentence, describe what the following article is about: Explaining that the number 1 also means 5 minutes and that the number 2 also means 10 minutes can be quite confusing. To help your kid understand this concept, pretend that the numbers are double agents with a secret identity, like Clark Kent and Superman. For example, tell your kid that the secret identity of number 1 is 5. Then have them write down a small number 5 next to the number 1. Repeat this for each number. Make sure to point out that you are counting by 5s. Go over each number's secret identity by singing your special "Count by 5s" song. Tell your kid that the numbers' secret identities come out when the long hand, i.e., the minute hand, points at it. Keeping the hour hand still, point the minute hand at each number and say the associated minutes. Than have your kid repeat the process back to you. For example, point the minute hand at 2 and say, "It is 10 minutes now." Then point the minute hand at 3 and say, "It is 15 minutes now." Once your kid has the concept of the minute hand down, you will need to teach them how to read the hour and minute hands together. Start with simple times such as 1:30, 2:15, 5:45, and so on. Point the hour hand at a number, then point the minute hand at a number. Then say what time it is. For example, point the hour hand at 3 and the minute hand at 8. Tell your kid that the time is 3:40 because the hour hand is pointing at 3 and the minute hand is pointing at 8. Reinforce the idea that because the minute hand is the secret identity hand, it reads as 40 and not 8. Repeat this activity until your kid gets the hang of it. Once your kid understands 5-minute intervals, add 4 tic marks between each interval. Start by writing 1, 2, 3, and 4 next to the tick marks between the 12 and 1. Encourage your child to fill in the rest of the minutes, counting out loud as you go. Then point the minute hand at a non-5 minute and the hour hand at an hour. Read the time. For example, point the minute hand at the fourth tick mark and the hour hand at 3. Tell your kid that the time is 3:04. Repeat this process until your kid understands how to read the tick marks on the clock. With your child, make a list of 5 to 7 activities with their associated times. Have your kid move the hands of the clock to reflect the activities' correct times. It is okay to help your kid in the beginning. Just make sure to repeat the activity until your kid can point the hands at the right numbers without your help. Encourage your kid by rewarding them for doing a good job. Take them to the park or to the ice cream shop to celebrate a productive lesson. Once your kid has mastered the activity on their handmade clock, move to the analog clock that does not have the numbers' secret identities. Repeat the activity with this clock to see how well your kid has mastered the concept of telling time.
Summary: Explain the double meaning of the numbers. Explain the minute hand's role. Demonstrate how to read the hour and minute hand together. Add tick marks for the non-5 minutes. Quiz your child. Make it challenging.

In one sentence, describe what the following article is about: Your screw should be long enough to penetrate completely through the wood and at least 1 inch (2.5cm) into the concrete. Measure the depth of your wood and concrete objects, and purchase screws that will fasten the wood securely. Although 1 inch (2.5cm) of concrete penetration is the minimum, deeper penetration will result in a stronger hold. The longer your screws are, the tighter they will connect the wood and concrete. Concrete screws are the newest method of fastening wood to concrete and generally the most popular because they are easy to remove. The holes should be approximately the same diameter as the screws that you're using. Drill completely through the wood and about 14 inch (0.64cm) deeper than the screw's length into the concrete. Mark the holes in the concrete and wood using a permanent marker first to make sure your holes are precise. Blow the residual dust out of the concrete hole using a vacuum or syringe blower. Copper wire ensures that the concrete screws will fit tightly into the hole. Cut a piece of copper wire approximately the same length as the concrete and wood hole, and thread it through the holes before you drive the screw in. Use a drill or screwdriver to drive the screw completely through the wood and concrete holes. If you are driving multiple screws, use the first screw you drive in as a test screw to make sure the hole is deep enough and you've used enough wire. You will know that you have used enough copper wire if the screw fits tightly into the hole and the connection between the wood and concrete is not loose or wobbly. Thread extra copper wire through the hole if it's too large for the screw.
Summary:
Select concrete screws based on the length of the intended hole. Predrill holes into the concrete and wood. Insert a piece of copper wire into the holes. Drive the screw through the wood and concrete.
