__Key Concepts__ 1. Count, read and write whole numbers 0 - 100. Identify the place value for each digit. Count to 100 by ones, twos, fives and tens. (rote counting). 2. Recognize and show fractions equal to one-half; one-third; and one-fourth. 3. Know addition and the corresponding subtraction facts (fact families). Solve addition/subtraction problems in everyday situations with one and two digit numbers. 4. Make estimates of objects in a set up to and including 50. 5. Order whole numbers from least to greatest value 0 - 100. 6. Measurement: Determine the length, width, and height of objects with standard units of measurement. Use a thermometer. 7. Time: Tell time to the nearest hour and half-hour with analog and digital clocks. (short hand is the hour hand; the long hand is the minute hand.) Name and order days of the week, months of the year. 8. Money: Identify and know the value of coins (pennies, nickels, dimes, quarters). Count coins by their value and be able to make exchanges of coins. (5 pennies = one nickel) 9. Geometry: Identify/name 2 dimensional geometric shapes (circle, triangle, square, rectangle, trapezoid, rhombus, hexagon) and find/name 2-D figures in real life. Identify/create lines of symmetry. (Look around the classroom, can you find a rectangle, etc.? If we fold this triangle in half perfectly and open it up again, do you see the line of symmetry?) 10. Identify a pattern based on shape, size, color. sound, or number. (Use beads and string them in a pattern; red, blue, green, red, blue, green, etc.) 11. Data: Describe/interpret data in a bar graph or pictograph. Gather/organize/sort/count/display data. (Be able to tell which category has the most = tallest bar. Create a bar graph by coloring squares that reflect the class activity.) 12. Probability: Decide if something is likely, unlikely, or certain.
