Mathematical Thinking Continuum
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.
- Uses known answers to find other answers.
- Subtracts on a 300 chart and with a calculator.
- Adds and subtracts multiples of ten.
- Distinguishes between geometric patterns and random designs.
- Distinguishes between mirror symmetry and rotational symmetry.
- Collects, represents, and interprets data.
- Estimates totals and differences.
