1. Number: Counting
Learning Objectives:
Recognize and work with increasing and decreasing number sequences involving 2s, 3s, 5s, and 10s.
Understand and describe patterns using place value.
Identify missing elements in number sequences.
Activities:
Daily counting warm-up sessions.
Skip counting exercises using a calculator and hundreds chart.
Students investigate number sequences starting from various points, particularly focusing on sequences that increase or decrease by 3s, 5s, and 10s.
Recognition and description of patterns identified in these sequences, with an emphasis on place value.
Activity 1: Daily Warm-up Counting
- Objective: To practice increasing and decreasing number sequences.
- Materials: A number line or hundreds chart (optional).
- Instructions:
- Begin each class with a short 5-minute warm-up. Ask students to count aloud together, starting at different points (e.g., 50, 125, 300).
- Alternate between increasing sequences (e.g., count forward by 2s, 3s, 5s, or 10s) and decreasing sequences (e.g., count backward by 2s, 5s, or 10s).
- Vary the starting points to challenge students (e.g., count by 5s starting at 37, count backward by 3s from 112).
Activity 2: Skip Counting with a Calculator
- Objective: To reinforce skip counting and introduce pattern recognition.
- Materials: Calculators, hundreds chart.
- Instructions:
- Students use a calculator to skip count by pressing the “+” button followed by the number they are skip counting by (e.g., for counting by 3s, press
3 + = = = repeatedly). - Have students record the numbers generated and mark them on a hundreds chart.
- Ask students to identify any patterns in the numbers they have highlighted.
Assessment Evidence:
Students identified several number sequences that increase by 10s from a three-digit starting point.
Descriptions of patterns using everyday language and mathematical terminology.
