Mathematical Thinking (Introduction, 3rd)

• Counts and groups quantities to make 100.
• Becomes familiar with number patterns on the 100 chart.
• Explores materials, including the calculator, to be used throughout the curriculum as tools for solving problems.
• Uses grouping to count.
• Constructs symmetrical patterns.
• Learns the addition combinations from 1+1 to 10+10.
• Develops and uses strategies to combine and compare quantities.
• Explore what happens when you add or subtract 10 or 20.
• Explore what numbers can be divided evenly.
• Reviews the values of coins and finds the values of collections of coins.
• Sorts and classifies information.
• Collects, records, and represents data.
• Explores the characteristics of odd and even numbers and how they behave when combined.
• Works with wholes and halves.
• Develops awareness of the decimal point and its meaning.

Mathematical Thinking (Introduction, 4th)

• Groups things for more efficient counting.
• Records numbers for more efficient mental arithmetic.
• Finds how many more are needed.
• Estimates how many hundreds in the total of a group of three-digit numbers.
• Recognizes values of U.S. coins and groups coins for more efficient counting.
• Recognizes the decimal point on the calculator.
