A seven years old learner is expected to:
- Perform addition and subtraction within 100 to solve one- and two-step word problems involving situations of adding to, following the rule, taking from, putting together, taking apart, counting back and front, and comparing, with unknowns in all positions,g., by using diagrams and equations with a symbol for the unknown number to represent the problem.
- Use mental strategies to add and subtract within 20. Fluently perform the sum and difference of two one digit numbers.
- Apply strategies such as counting on; making ten (e.g., 7 + 6 = 7 + 3 + 3 = 10 + 3 = 13); decomposing a number leading to a ten (e.g., 12 – 4 = 12 – 2 – 2 = 10 – 2 = 8); relating the relationship between addition and subtraction (e.g., knowing that 7 + 5 = 12, one knows 12 – 7= 5); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
- Classify the group of objects (up to 20) as an odd or even number of members, e.g., by circling the pair of objects or crossing out 2 at a time.
- Perform addition to find the total number of objects arranged in rectangular arrays with up to 5 rows and up to 5 columns; Express the total as a sum of equal addends using equation.
- Recognize and write fraction from the picture. Sketch the fraction.
- Compare fractions using symbols such as , and
- Recognize that the three digits of a three-digit number represent amounts of hundreds, tens, and ones. For example, 237 means 2 hundreds, 3 tens and 7 ones.
- Count within 1000; skip-count by 5s, 10s, and 100s.
- Read and write numbers to 1000 using base-ten numerals, number names, and expanded form.
- Arrange two three-digit numbers based on meanings of the hundreds, tens, and ones digits, using >, =, and < symbols to record the results of comparisons.
- Use strategies based on place value, properties of operations, and/or the relationship between addition and subtraction to fluently add and subtract within 100.
- Perform addition and subtraction within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method. Recognize that in adding or subtracting three digit numbers, one adds or subtracts same place values; and sometimes it is necessary to compose or decompose tens or hundreds.
- Perform addition and subtraction mentally of 10 or 100 from a given number between 100 and 900.
- Discuss why addition and subtraction strategies work, using place value and the properties of operations.
- Identify the appropriate tools such as rulers, meter sticks and measuring tapes, to measure the length of an object.
- Identify the attribute to be measured and choose the appropriate unit of measurement for length. For example, the length of the tip of the pencil is measured in centimeters.
- Perform addition and subtraction within 100 to solve word problems involving lengths that are given in the same units, e.g., by using pictures (such as drawings of rulers) and equations (symbols will be used for unknown number) to represent the problem.
- Use number line diagram to perform addition and subtraction within 100.
- Understand the attributes of time and apply appropriate measurement.
- Tell time to the quarter hour. Tell time as the minutes before the hour. tell and show times to 5 minutes.
- Describe times of events as A.M and P.M. Determine how much time has passed from start to finish. Identify noon and midnight. Solve simple problems of elapsed time.
- Analyze bar graph to find information in order to solve simple put together, take-apart, and compare problems. For example, how many children have cycle?
- Organizes data into simple graphs such as pictographs and bar graphs.
- Identify plane figures. Describe and classify triangles, quadrilaterals, pentagons, hexagons, and cubes.
- Divide a rectangle into rows and columns of same-size squares and count to find the total number of them.
- Divide circles and rectangles into two, three, or four equal shares, define the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Discover that equal shares of identical wholes need not have the same shape.
