Juan has a dime and eleven pennies in his piggy bank. His sister has 3 nickels and 4 pennies in her bank. Who has saved the most money?
1.M.6c
Distribute play money (or coins cut from a handout). Ask students the following question:
I'm thinking of three coins that equal 15˘. What are they? Have students then display the coins that answer the riddle. Students may take turns creating their own riddles for others to solve.
1.M.7 Recognize specific times (morning, noon, afternoon, evening)
1.M.7a
Fold paper into four sections. Draw a picture of something you usually do in the morning, at noon, in the afternoon, and in the evening.

Give students pictures of seasonal and holiday events. Have them match the pictures to cards with the names of seasons and months printed on them.
1.M.10b
Draw pictures to represent each of the four seasons and name the months included in each season.
Students will develop strategies for estimating measurements.
Estimation
1.M.11 Select and use nonstandard units to estimate measurements
1.M.11a
Ask students how they could measure the circumference of a pumpkin or large ball.
1.M.11b
How many shoelengths long is the classroom? Estimate, then measure.
Statistics and Probability Strand
Students will collect, organize, display, and analyze data.
1.S.1a
Guide students to suggest ideas for questions about themselves (e.g., favorite color, type of pet, etc) and discuss the responses.
1.S.2 Collect and record data related to a question
1.S.2a
Have students name their favorite colors and organize the data as a pictograph.
Organization and Display of Data
1.S.3 Display data in simple pictographs for quantities up to 20 with units of one

Make a pictograph of favorite colors with a smiley face on the graph representing the favorite color of each student.
1.S.4 Display data in bar graphs using concrete objects with intervals of one
1.S.4a
From a container of pattern blocks use a cup to scoop some out. Sort, then record the number of each pattern block piece on a bar graph.
1.S.5 Use Venn diagrams to sort and describe data
1.S.5a
Using a collection of real fruit or pictures of fruit, discuss ways the fruit can be sorted. Next, place overlapping loops of yarn on the floor to create a Venn diagram. Help the students understand how a Venn diagram can be used to show that something might be part of one group, two groups, or not belong in either group. Use the Venn diagram to organize the fruit. Some possible groups are: yellow fruits, fruits with peels, fruits with seeds, or round fruits, etc.
