  1. CLASS II

  2. “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

  3. NUMBER CONCEPTS 101-1000 • NUMBER NAMES AND NUMERALS • 134 - One hundred thirty- four • PLACE AND PLACE VALUE H T O PLACE PLACE VALUE 1 3 4 tens 30 • BEFORE AFTER BETWEEN 133 134 135

  4. 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

  5. ABACUS HTO 134 134 = 1 hundred + 3 tens + 4 ones = 100 + 30 + 4

  6. ADDITION • CONCRETE OBJECTS

  7. ADDITION • PICTORIAL ADDITION • NUMBER LINE ( FORWARD COUNTING) • HORIZONTAL ADDITION

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

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

  10. SUBTRACTIONconcrete objects

  11. SUBTRACTION • PICTORIAL • NUMBER LINE (BACKWARD COUNTING) • HORIZONTAL SUBTRACTION

  12. VERTICAL SUBTRACTIONTWO DIGIT WITH TWO DIGIT (WITHOUT BORROWING) T O 4 6 -3 5 _____ 1 1

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

  14. MULTIPLICATION CONCRETE OBJECTS

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

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

  17. MULTIPLICATION • HORIZONTAL

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

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

  20. measurement

  21. measurement Weight /mass…….gram(g) /kilogram(kg) Length …centimetre(cm) /metre(m)/kilometre(km) Capacity….millilitre (ml) /litre (l)

  22. Time

  23. Calendar- 2014 • A)What day will be the 3rd of this month? • B) How many Sundays are there in this month? • C)Which month comes after this month?

  24. DATA HANDLING1. Santosh keeps hens. He has made a list of the eggs he gets every day. Study the list and answer the questions.
