By the end of the school year, all students should be able to:
■ Count to 1,000 by 25s (25, 50, 75, …); 50s (50, 100, 150, …); and 100s (100, 200, 300, …).
■ Multiply single digits fluently. For example, solve problems such as 3 × 4 = 12 and 6 × 9 = 54 without having to count or add groups of numbers.
■ Divide single digits fluently. For example, solve problems such as 45 ÷ 5 = 9, without having to count or subtract.
■ Identify even and odd numbers. Know what happens when even and odd numbers are added and subtracted. For example, adding two odd numbers results in an even number, and subtracting an odd number from an even number results in an odd number.
■ Understand that fractions are equal parts of a whole unit or a group; for example, 1/4 is one of four equal parts.
■ Compare fractions such as 1/2, 1/3, and 1/4, and find their approximate places on a number line.
■ Use the correct words, such as “circle,” “triangle,” “square,” “sphere,” “cube,” or “trapezoid,” when talking about geometrical shapes.
■ Use a ruler or yardstick to measure to the nearest half inch, inch, foot, yard, or other standard unit.
■ Use digital and traditional analog clocks to tell time to the nearest minute.
■ Count coins and dollars. Use the correct currency symbols ($, €) to represent amounts, such as $2.36.
Learning at Home
Ask your child to count out the dollars and coins for things you pay for in cash, such as magazines from the newsstand or movie tickets.
Challenge your child to find all the devices that tell time in your home. Look for clocks on stoves or microwaves, cable boxes, DVD players, computers, iPods, cell phones, and wristwatches. Together, reset them so they all display the same time.
Visit the interactive exhibit Mathematica: A World of Numbers with your child at the New York Hall of Science in Queens, www.nyscience.org.
Weigh and measure your child to record growth over time.
Provide opportunities to do puzzles.
