2 CLASS II

3 “God wrote the universe in the language of mathematics.” - Galileo Galilei Mathematics may not teach us how to add love or minus hate but it teaches us that every problem has a solution. “Only in the world of mathematics do two negatives multiply into a positive.” - Abby Morel

4 NUMBER CONCEPTS 101-1000 NUMBER NAMES AND NUMERALS 134 - O ne hundred thirty- four PLACE AND PLACE VALUE H T O PLACE PLACE VALUE 1 3 4 tens30 BEFORE AFTER BETWEEN 133 134 135

5 NUMBER CONCEPTS 101-1000 DESCENDING ORDER ASCENDING ORDER BIGGEST /SMALLEST NUMBER FILL IN THE MISSING NUMBERS SKIP COUNTING ODD AND EVEN NUMBERS ORDINAL NUMBERS AND ORDINAL NUMBER NAMES

6 ABACUS H T O 134 134 = 1 hundred + 3 tens + 4 ones = 100 + 30 + 4

7 ADDITION CONCRETE OBJECTS

8 PICTORIAL ADDITION NUMBER LINE ( FORWARD COUNTING) HORIZONTAL ADDITION

9 VERTICAL ADDITION Two digit with two digit (without carry over) T O 4 5 + 3 3 ---------- 7 8 ----------

10 Addition 2- digit with 2-digit (With carry over) T O +1 4 5 + 3 6 __________ 8 1 ___________

11 SUBTRACTION concrete objects

12 SUBTRACTION PICTORIAL NUMBER LINE (BACKWARD COUNTING) HORIZONTAL SUBTRACTION

13 VERTICAL SUBTRACTION TWO DIGIT WITH TWO DIGIT (WITHOUT BORROWING) T O 4 6 -3 5 _____ 1 1

14 TWO DIGIT WITH TWO DIGIT (WITH BORROWING) T O 4 11 5 1 3 6 ____ 1 5

15 MULTIPLICATION CONCRETE OBJECTS

16 MULTIPLICATION Multiplication means repeated addition of the same numbers. Addition Sentence: 4 + 4 + 4 = 12 Multiplication Sentence : 3 4 = 12

17 Building tables Table of 1,2, 3, 4, 5, 6 & 10 Table of 5 1x 5= 5 2x5 = 10 3x5 = 15 10x 5 = 50

18 MULTIPLICATION HORIZONTAL

19 VERTICAL Two digit with one digit (without regrouping) T O 2 1 x 3 ---------- 6 3 ----------

20 VERTICAL Two digit with one digit (with regrouping) T O +1 2 5 x 3 ---------- 7 5 ----------
