Elementary teachers can use the following suggestions to introduce or give students extra practice with mathematics skills related to numbers and operations or algebra.
Practice Grouping and Adding and Practice Skip-Counting
Pass out 100 paper or felt shamrocks to individual students, student pairs, or groups of students. Have students practice grouping by dividing 100 in different ways, such as 2 groups of 50, 4 groups of 25, 5 groups of 20, and 10 groups of 10.
Next, have students practice skip-counting. Ask students to stack the shamrocks in groups of twos, fives, or tens. Have them skip-count each time to count the total amount.
Finally, stick felt shamrocks on a felt board or draw them on the board in different arrangements of rows and groups. Refer to Math for All Seasons by Greg Tang [Scholastic Press, 2002] for ideas for different arrangements. Then, have students think through each problem and use different time-saving techniques for grouping and adding to count how many shamrocks are shown in each case. Prompt with questions such as, "How many groups of 3 can be found?"
Practice Addition and Subtraction Skills
Have students use shamrock manipulatives to solve simple addition and subtraction problems. Use real-world scenarios to make problems interesting. For example, Jane and Ethan are searching for shamrocks in a field. Jane finds 5 and Ethan finds 3. How many shamrocks have they found in all?
Practice Multiplication Skills and Division Skills
Point out that each shamrock has 3 leaves. Discuss how students can multiply the total number of shamrocks by 3 to find out quickly how many leaves there are in all in a group of shamrocks. Then show how students can place 3 hearts (leaves) together to build 1 shamrock. Have students use paper green heart manipulatives and the shamrock manipulatives to solve multiplication and division word problems such as, How many leaves do 5 shamrocks have in all? or How many leaves does a person need to build 3 shamrocks?
Practice Fractions
Pass out drawings of an outline of a three-leaved clover. Have students practice fractions by coloring in 1/3, 2/3, and then 3/3 of the leaves.
Then, pass out drawings of groups of shamrock outlines and have students color in certain fractions of the total amount. For example, pass out a drawing of 6 shamrocks and have students color in 1/2 (or 3) of the shamrocks.
Pass out light green paper and dark green paper shamrocks. Have students arrange them in groups to show different kinds of fractions. For example, have them show 6 shamrocks where 1/3 (2 shamrocks) are dark green and 2/3 (4 shamrocks) are light green.
Practice How to Finish Growing Patterns
Form growing patterns with felt shamrocks on a felt board or by passing out drawings of rows, columns, or groups of shamrocks. For example:
- a column of 1 shamrock, a column of 2 shamrocks, and a column of 3 shamrocks
- a row of 2 shamrocks, 4 shamrocks arranged 2 x 2, and 6 shamrocks arranged 2 x 3
Ask students to use shamrock manipulatives or to draw in more shamrocks to show what comes next in each growing pattern.
Practice How to Create Patterns
Pass out a number of shamrocks of various sizes (big, medium, and small), of various shades of green, and made from various materials and textures (cardboard, felt, construction paper, or tissue paper). Use fewer variations for struggling students and more for more advanced students.
Demonstrate how to alternate two kinds of shamrocks to create a simple pattern. Ask students to identify which shamrock comes next in the pattern. Then, have students practice creating and finishing their own patterns. The shamrocks can be used over and over or students can glue their finished patterns to large sheets of paper.
Students can also use shamrock stickers or use different shamrock-shaped potato stamps to create patterns. Additionally, students can practice sorting the shamrocks by size, color, and texture as an enrichment activity.
Using shamrocks in math activities on this March 17th Irish holiday will capture students' attention and keep them focused and excited about mastering new mathematics skills.
For other St. Patrick's Day lesson plans and activities, elementary teachers and use Irish folktales to teach reading comprehension skills or practice writing skills, or plan a children's party.
