2010-2011 1st Grade Math Objectives 1. a. Students will read, write, and count numbers by 1s, 2s, 5s, and 10s, to 100. b. Students will recognize number words 0-12. c. Students will compare number sets to 100. 2. a. Students will demonstrate the ability to complete addition and subtraction facts for sums to 20 using one or more strategies. (number lines, touchpoints, counting on, counting down, doubles, doubles +1, making 10, adding to 10, fact families, and others) b. Students will describe or model the strategies they use to compute addition and subtraction facts for sums to 20. c. Students will use strategies to develop fluency in addition and subtraction problems for sums to 20. (Students become efficient enough with strategies that answers come more quickly and more accurately, especially in addition.) d. Students will describe the relationship between addition and subtraction. (with concepts such as fact families) e. Students will apply the commutative and associative properties of addition. (using “turnaround facts” and number groupings) (associative property: grouping of addends doesn’t affect the sum (9+5) +1 equals (9+1) +5; often used in making 10) (commutative property: order of addends doesn’t affect the sum 4+7 = 7+4) f. Students will memorize addition doubles facts. 3. a. Students will represent or model addition and subtraction word problems using pictures, objects, or symbols. b. Students will write a complete number sentence for a given addition or subtraction word problem. c. Students will describe the effects of adding and subtracting whole numbers. (Adding makes more.) 4. Students will create, recognize, describe, and extend a variety of patterns. 5. a. Students will write the days of the week in order using a word bank. b. Students will interpret the calendar by locating dates on the calendar and correlating them to the days of the week. c. Students will recognize elapsed time in days. 6. Students will gather information, construct, read, and interpret data in simple graphs and charts, such as pictographs, bar graphs, and tally graphs. 7. Students will recognize and apply the concept of time to the hour and half-hour using analog and digital clocks. 8. a. Students will recognize a penny, nickel, dime, quarter, and half-dollar and know each coin’s value. b. Students will count to $1.00 with a single type of coin. (10 dimes, 20 nickels, & 4 quarters) c. Students will count mixed coins (dimes, nickels, & pennies) whose total value is up to 50¢. 9. Students will recognize that two-digit numbers are made up of tens and ones. 10. Students will solve 2-digit addition and subtraction problems without regrouping and describe the strategies used. (adding ones first) 11. a. Students will recognize 1/2, 1/3, and 1/4 of a shape. b. Students will identify halves as 2 equal parts, 3rds as 3 equal parts, and 4ths as 4 equal parts. c. Students will share a group of objects fairly. 12. Students will recognize odd and even numbers. 13. a. Students will identify the following 2-D shapes: circle, triangle, trapezoid, rectangle, rhombus, and square. trapezoid – red pattern block; 2 of 4 sides are the same distance apart (parallel) and 2 are not rhombus – orange, blue, and tan pattern blocks; all 4 sides are the same length and opposite sides are the same distance apart (parallel); a square is a rhombus with right angles b. Students will recognize sides and corners of the 2-D shapes in 13 a. c. Students will identify shapes and objects which have symmetry. d. Students will use manipulatives to model flips. 14. a. Students will select the appropriate tool for measuring size (ruler), capacity (cup), weight (scale), and temperature (thermometer). b. Students will measure objects using standard and non-standard units of measurement. 15. Students will recognize and use ordinal numbers. 16. a. Students will identify the following 3-D shapes and their correlating faces: sphere, cube, cone, pyramid, rectangular prism, and cylinder. b. Students will relate the 3-D shapes to real-life objects. 17. Students will describe, name, and interpret relative positions in space (left, right) 18. a. Students will classify objects by size or number. b. Students will sort and classify objects according to their attributes (size, shape, color). 19. Students will compose or decompose whole numbers to 20 using strategies such as known facts, doubles, close to doubles, tens and ones, and others. (create or break apart numbers to form equivalent representations. Ex. 16 = 8+8 or 10+6 or 20-4 or 4x4)
