Pre-K-2
Children use pennies, nickels, dimes, and quarters to model amounts to 70 cents. Next they answer money puzzles and estimate the number of pennies in a jar. They also add to the word wall.
Pre-K-2
This final lesson of the unit reviews the work of the previous lessons. Children discuss and model prices and the words on the word wall and play games to facilitate continuing practice. They add to their portfolio and listen to another children’s book. Questions for summative evaluation are suggested.
Pre-K-2, 3-5
In this lesson, students make patterns with objects, read patterns and find patterns in the environment. They should be encouraged to classify patterns by type (i.e. AAB, ABC). They continue learning about patterns by extending a given pattern, identifying missing elements in a pattern, and recording a pattern.
Pre-K-2
Students extend their knowledge of linear patterns by recognizing and discussing familiar patterns. Students make auditory and visual patterns from names. An art activity is suggested as an extension.
Pre-K-2
This final lesson reviews the work of the previous lessons. Students explore patterns in additional contexts and record their investigations. Students will rotate through center activities. Teachers may add other centers they feel will benefit the students.
Pre-K-2
In this activity, students plan a series of moves that will navigate a
ladybug through a maze. Their plans turn the ladybug at the appropriate
corners and keep it on a path without crossing the walls. This activity
helps students gain experience in estimating length and angle measures.
Pre-K-2
The students make sets of pasta shapes and count some away, then record the subtraction in vertical and horizontal formats. They draw a set and cross out some shapes, then write in both formats the subtraction that the drawing represents.
Pre-K-2
This lesson encourages the students to explore the familiar set model of subtraction. The students write story problems and find differences using sets, including subtracting all and subtracting zero. They record the differences in a chart.
Pre-K-2
In this lesson, the students find differences using the number line, a continuous model for subtraction. [Number can be considered in two ways: discrete and continuous. The counting and set models use the discrete form of number.] Students are encouraged to predict differences and to compose puzzles involving subtraction.
Pre-K-2
This lesson encourages students to explore another meaning of subtraction, the balance. They use subtraction facts to generate related addition facts and explore at the concrete level the idea of subtraction as the inverse of addition.
