2 1 s 1-2 Objective Investigate length and nonstandard length measurement Materials ribbon; tape; chart paper; marker; Content Area Flip Chart, p. 7; plants of different heights Share and Read Tape a length of ribbon on the wall that is about the average height of a child. Title one piece of chart paper taller and another shorter. Tape them on either side of the ribbon and read them aloud. Stand beside the ribbon. Ask: Am I taller than the ribbon or shorter? Ask one child at a time to stand by the ribbon. Encourage children to describe the comparison by saying taller than the ribbon or shorter than the ribbon. Have children write their name on the appropriate piece of paper. Display Content Area Flip Chart, page 7. Help children to circle the objects that are longer than the pencil. Talk About It Display several plants. Help children to order the plants from shortest to tallest. Objective Investigate length and weight Materials Math Songs CD: Track 9 Sing Can You Tell Me Now? Play Can You Tell Me Now? on Math Songs CD: Track 9. Begin by finding two objects in the classroom to compare, using the concepts of tall and short, long and short, light and heavy, and holds more and holds less. Example: The teacher is tall and children are short or the crayon is light and the table is heavy. Note: Children will further explore weight next week. As they begin to grasp the concept, ask children to think of items outside the classroom and identify measurable attributes. Examples: A pond holds more water than a fish tank which holds less water. Or a tree is tall compared to a flower which is short. Include physical motions to illustrate the attributes, such as holding hands far apart to represent long and closer together to represent short. 2

3 1 Objectives Investigate length and nonstandard length measurement Materials modeling clay, two-color counters (red/yellow) Long or Short? Have children work in pairs. Distribute two balls of modeling clay and two counters to each pair. Have children divide the modeling clay into ten equal-size pieces and then make five long ropes and five short ropes. Tell children to each take one counter and flip it. If the two counters land on different colors, the player with yellow takes one long rope. The player with red takes a short rope. If the counters are the same color, neither player takes a rope. After children have taken five ropes, each child joins his or her five modeling clay ropes into one continuous rope. Partners compare their final ropes to determine whose rope is longer and whose rope is shorter. Objectives Investigate length and nonstandard length measurement Materials yarn, craft sticks, connecting cubes Extension Activities Use the following activities to reinforce/extend the learning in upcoming days and weeks. Jump! Jump! Jump! Have children measure how far they can jump by lining up different size units (craft sticks, yarn, connecting cubes) along the edge of a string connecting starting and ending points. Ask children if they use more crafts sticks or connecting cubes to measure their jumps. Rulers Rule Distribute rulers to children. Explain their use. Have children find, measure, and sort objects in the room into longer than the ruler, shorter than the ruler, or the same length as the ruler. Which Is Longest? Give children an assortment of objects to order from shortest to longest. Model thinking aloud as you work beside the children to use the new math terms and problem solve.

4 2 s 1-2 Objective Investigate weight and measurement Materials 2 measuring cups, rice, plastic jars, materials of different weights, box Game Display two measuring cups--one empty and the other full of rice or another solid. Give each child an opportunity to hold both cups and then ask: Which is heavier? Which is lighter? Which is harder to lift? Display several plastic jars. Help children to use measuring cups to fill the jars with different materials, such as sand, water, soil, dried beans, and flour. Ask: Can you tell which is the heaviest by looking at the jar? Why not? What do you need to do? Help children compare weights and select the lightest and heaviest jars. Then ask them to arrange the jars in order of lightest to heaviest. Invite children to put six of the same objects in a box and feel its weight. Add a seventh object and ask: What happens when I put another object in the box? Is the box heavier or lighter? Continue with eight, nine, and ten objects. Objectives Investigate weight and measurement Materials chart paper Nature Walk Take the class on a walk outside the classroom to observe and compare the weights of various objects. As you locate certain objects during the walk, stop and allow chidlren to lift the items. Make sure that children lift a variety of objects that vary in weight and size, such as leaves, rocks, and balls. Allow children to try to pick up an object, such as a playground climber that is too heavy to lift, so that they understand how heavy some objects can be. Upon returning to the classroom, generate a list on chart paper of the items the children lifted. Then on another sheet of chart paper, classify these items into the following categories: too heavy to lift, heavy, not heavy. Guide children to use the word light to describe the weight of objects that were not heavy.

5 2 Objectives Investigate weight and measurement Materials balance scale, classroom objects Balance Scale Display a balance scale and explain how to use it. Tell children that if one object is heavier than another, the scale will dip lower. Model using two classroom objects. Provide an assortment of classroom objects of varying weights. Have children take turns selecting two objects, predicting which is heavier (or lighter) and then weighing the items on the scale to confirm their predictions. Place the balance scale in the Math Center for children to continue exploring weight in the upcoming weeks and months. Objectives Investigate weight and measurement Materials measuring cups and spoons, balance scale, rice, sand, water, cups. Extension Activities Use the following activities to reinforce/extend the learning in upcoming days and weeks. Measure It Provide an assortment of measuring tools in the Math Center, such as measuring cups and spoons. Have children measure out water, rice, or sand into cups. Suggest that they weigh two cups on a balance scale to compare the weights. Food Pass around various foods in small cups, such as apples, raisins, nuts, oranges, and crackers. Ask children which weighs the most. Have children weigh various foods to compare. Balance It Place a cup filled with trail mix on one side of a balance scale. Place an empty cup on the other. Tell children that they must scoop out the exact amount of trail mix so that the cups have equal amounts. This will be their snack for today.

6 s 1-2 Objective Investigate time and temperature Materials Content Area Flip Chart, p. 8; marker; clock with hands Objectives Investigate time Materials restaurant items Share and Read Ask: How do you know when it is day? How do you know when it is night? Discuss the sun rising and setting, and daytime activities and nighttime activities. Display Content Area Flip Chart, page 8. Identify the activities. Point to the smaller pictures and say: The sun rises in the morning. There is a full sun in the afternoon. And the moon and stars come out at night. Discuss how the weather can change the amount of sun and temperature. Guide children to draw a line to match the times of the day to the pictures. Talk About It Display a clock with hands. Point to each number and say it aloud. Ask questions such as: What time do you come to school? What time do you eat lunch? Move the hands on the clock to show that time of day. When Do We Eat? In the Dramatic Play Center, set up a restaurant. Discuss the types of food children order when they go out to eat. Have children identify breakfast foods, lunch foods, and dinner foods. Ask children when they eat breakfast; then ask when they eat dinner. Help children to identify that when they wake up, it is morning, and that is usually when people eat breakfast. Tell children that after school when they eat dinner, it is evening. Finally, tell children that in the middle of the day when they are eating lunch, it is afternoon. Tell half of the class that they are customers and the other half that they are waiters or waitresses who will have to take the order of the customers to see what they want to eat. Name a time of day and have the customers order a food that is typically eaten during that time. Then have children switch roles. 6

7 Objectives Investigate time and temperature Materials clock, timer, calendar, thermometer Objectives Investigate time and temperature Materials time line, daily calendar Measuring Devices Introduce and explain the use of important devices to measure time and temperature. Clock Point out the wall clock to children. Show them the moveable clock face. Let them move the hands around. Explain how the clock face is made just like the wall clock face. Show them how to set the hands on the clock face so they match the wall clock. Point out the times of activities throughout the day from this day on. For example, it is now 2 o clock. It is time for a snack. Calendar Explain to children that a calendar is another way to measure time. Point out how a calendar is divided into months and days. Continue to work with children to recite the months of the year and days of the week. Thermometer Explain the types and uses of a thermometer (one for measuring outside temperature, one for measuring body temperature). Use a thermometer to record the outside temperature for a week. Extension Activities Use the following activities to reinforce/extend the learning in upcoming days and weeks. Time Line Help children make a time line of their day. Place a sun on one end of the time line and a moon on the other end. List events in order from morning until night. Calendar Time During the daily calendar time, reinforce the words yesterday, today, and tomorrow. Picture Sorts Make or find pictures of daytime and nighttime activities for children to sort. They can also sort foods by time of day eaten (breakfast, lunch, dinner). Daily Routine Use the daily routine to reinforce temporal words, such as We will go outside to play after we have our snack. 7
