This lesson on mathematics introduces the students to clocks and the importance of telling time, as well as different forms of measurements and how they assist us in our daily activities.

"Time"
Cartoon characters Daniel and Kerry want to buy their grandfather a hat for his birthday. As they arrive at the closed store, they realize the convenience of knowing store hours and how to tell time. This introduces the students to understanding the importance of knowing how to determine the time of day. Encourage students to talk about different activities of theirs require knowing the time and why it is important.

"Measurement"
The other concept that will be explored in this lesson is measurements. Kerry and Daniel must determine which bakery is closest to the park. Students are asked how they think this can be determined.
Hands-on activity - To begin, students will measure by using their footsteps. Students begin exploring measurements by walking heel-to-toe from one of a table to the other. Students count how many steps this requires. The short distance will help students focus on the measuring aspect and not a high number to remember. Note: Inches, centimeters, feet and meters are not mentioned in these lessons. This is to be the teacher's determination because of the difference in measurements in different school locations. The lesson is designed to explore measurements in an introductory fashion and is quite effective with or without these terms, whatever the teacher determines. As a challenge, students are then asked (by Challenge Pig) how they might measure from the ceiling to the floor. Talk about how impractical it is to measure some distances by walking.
Hands-on activity - Using paper and markers or crayons, students draw an outline of one of their feet. Cut these outlines out to create a measurement tool. Note: Crayons are suggested for this activity as markers may leave ink on shoes. Students are instructed to find something to measure using their footprint cutouts. Suggest they work as a team to measure longer distances, counting as they measure. The teacher may want to create a simple visual graph or record of their measurements on a chalk board or flipchart paper. Students can then compare their numbers and distances.
Touch-screen activity - Students must count the footsteps as shown on the Learning Station as Daniel and Kerry walk to each bakery. Which is closest?

"What Time is it? "
When Kerry and Daniel arrive at the bakery, they order a cake for their grandfather's birthday. The baker informs them that they will have to return after 3:00 but before closing time at 6:00. The children must think about how they will know when it is 3:00. Talk about the different ways they might determine the time.

"The Hat Store"
Kerry and Daniel's next stop is the hat store. As they try to choose a hat, they discover that hats come in many different sizes. The store clerk asks them what size their grandfather might wear. The children are told to go home, determine the hat size, but return by the 5:00 closing time. An analog clock on the wall shows the time at 3:00. Challenge Pig asks the students to think and talk about the difference between analog and digital clocks. Some students may not know that they are both clocks.
Optional activity: If possible, provide an example of each clock. Compare the appearance of the clocks while they show the same time.

"Measuring Grandpa's Head"
Kerry and Daniel go home to determine the size of Grandpa's head. While Grandpa is napping, the children must decide how to measure his head. Ask students if they can think of a way to solve this problem. Remind students to think about their answer and answer in a complete sentence. Also remind them that they are using mathematics and their 'thinking' skills to figure out a solution.
Hands-on activity - Provide students with lengths of yarn, ribbon or string for this activity. Students then measure their own heads' circumference and compare. Would Grandpa's head be the same size as theirs? Why? The teacher can then cut the strings at the appropriate measure point so that students can attach them to the board or a table to compare. Does hair make a difference? How long would the measurement stretch if they were combined? How many students would wear the same sized hat?
Note: A videotaping activity is NOT provided in this lesson so that teachers can decide when and what activity to videotape. An explanation of how students determined measurements using their footprints OR the ribbons are two options.

"Telling Time"
Clocks are now introduced as the lesson continues its focus on time measurement. The parts of a simple clock are illustrated and identified on the Learning Station. Students are instructed to count the numbers on the clock together. Minutes and seconds are then introduced and described. Encourage students to listen carefully to the instructions as they demonstrate how long these time elements last. Students then count seconds and minutes to get an understanding of their length.
Hands-on activity - A simple clock is illustrated on the Learning Station to be used as a guide as students make their own clock faces. Round paper plates work very well for this project. Instruct students to write the numbers where they belong. Correct placement of the numbers is easiest if they write the 12 and 6 first, then the 3 and 9, followed by the remaining numbers. Using strips of paper, students then attach the hands. Remind them that one is longer than the other. Attach the hands with a bendable clip that attaches notebook paper together.

"How Much Time Do Daniel & Kerry Have?"
Activity - Students are then instructed to move the hands of their clocks to designated times. Older students can be encouraged to assist the younger ones in this task. Students must listen carefully to the questions as they are asked.

"Buying Grandfather's Hat"
"Buying Grandfather's Cake"
As Kerry and Daniel arrive at each store, they are shown the different times on different clocks. Students can adjust their clocks accordingly along with the story.

"Party Game"
Touch-screen game - Students must 'race against the clock' by moving Kerry and Daniel from place to place on the Learning Station as instructed. Each place is highlighted to show where to go next. If they bump into anything, the cake will fall and they must return to the bakery for another cake. A 'reset' button allows the game to be played again. The Fastforward button on the toolbar must be activated to advance.

"When You Get Home"
Review with the students the names of the parts of the clock. Remind them to describe their clocks to their families when they get home. Also suggest they show their parents how to measure different surfaces using their cutout feet and ribbons.
