Real Life Link: When Nandika's family buys something for ₹25,499, she can now read it perfectly - Twenty-five thousand four hundred and ninety-nine rupees!
Day 3 - WedComparing & Ordering Numbers
Concept
To compare numbers: first count digits (more digits = greater). If same digits, compare left to right digit by digit. Use symbols >, <, =. Ascending = smallest to largest. Descending = largest to smallest.
Examples
Compare 54,321 and 54,312. Both have same digits - compare: 3 vs 3, 2 vs 1. So 54,321 > 54,312. Arrange 34,500 - 34,050 - 35,400 in ascending order.
Practice
Put >, < or = : 67,890 __ 67,980 - 45,000 __ 45,000 - 99,999 __ 1,00,000. Arrange in descending order: 23,450 - 23,045 - 23,540 - 23,405.

Game Idea: Papa calls out two big numbers. Nandika gives the answer in under 5 seconds - faster each day!
Day 4 - ThuRounding & Estimation
Concept
Rounding to nearest 10: look at ones digit. 0-4 = round down, 5-9 = round up. Rounding to nearest 100: look at tens digit. Rounding to nearest 1,000: look at hundreds digit. Estimation = quick approximate answers using rounding.
Examples
Round 4,567 to nearest 10 → 4,570. To nearest 100 → 4,600. To nearest 1,000 → 5,000. Estimate: 3,456 + 2,789 ≈ 3,500 + 2,800 = 6,300.
Practice
Round to nearest 10: 4,564 - 8,237 - 1,995. Round to nearest 100: 34,450 - 67,830. Estimate the sum: 4,512 + 3,689.

Check Trick: Always estimate first! If your answer is very different from the estimate - you made a mistake. Find it!
Day 7 - TueSubtraction with Regrouping (Borrowing)
Concept
When the top digit is smaller than the bottom digit, we "borrow" 1 ten from the next column. Step by step: start from Ones, go left. If 0s are in the way, we may need to borrow from farther left. Show this patiently with examples.
Examples
Solve: 80,000 - 34,567 (tricky - all zeros!). Show borrowing step by step. Also: 65,302 - 28,476. Check: 28,476 + answer should = 65,302.

Day 21 - MonFractions - Types & Equivalent Fractions
Concept
Types: Proper (¾), Improper (7/4), Mixed (1¾), Like (same denominator), Unlike (different denominators), Unit fraction (1/n). Equivalent fractions = multiply or divide numerator and denominator by same number. Simplest form = divide by HCF.
Examples
Equivalent to ⅔: 4/6, 6/9, 8/12. Simplify 18/24: HCF=6, → 3/4. Convert 11/4 to mixed: 2¾. Convert 3⅖ to improper: 17/5.
Practice
Find 3 equivalents of ⅗. Simplify: 12/16 - 20/25 - 36/48. Convert: 17/5 to mixed - 4⅗ to improper.

Real Life: Recipes use fractions! "Add ¾ cup flour and ½ cup sugar." Help Mama cook this weekend and practise fractions deliciously!
Day 24 - ThuIntroduction to Decimals
Concept
Decimals = fractions with denominators 10, 100, 1000. 0.3 = 3/10. 0.45 = 45/100. 1.7 = 1 and 7/10. Decimal place values: Ones . Tenths Hundredths. Comparing decimals: same as whole numbers - compare digit by digit from left. Adding zeros after the last decimal digit doesn't change value (0.5 = 0.50).
Examples
Write 0.75 as a fraction → 75/100 = ¾. Write ⅖ as decimal → 0.4. Compare 0.45 and 0.5: 0.45 = 0.45, 0.50 = 0.50. So 0.5 > 0.45.
Simplify 24/36. Add ¾ + ⅝. Subtract 2½ - 1¾. Write 0.35 as fraction. Compare 0.7 and 0.69.

Week 6 - Measurement, Time, Money & Geometry
Length - Weight - Capacity - Time & Calendar - Money - Shapes & Area
Day 26 - MonLength, Weight & Capacity
Concept
Length: km → m → cm → mm (×1000, ×100, ×10). Weight: kg → g (×1000). Capacity: l → ml (×1000). Converting: multiply when going to smaller unit, divide when going to larger unit. Word problems involve adding or subtracting measurements.
Examples
3.5 km = 3,500 m. 2,750 g = 2 kg 750 g. 4 l 500 ml + 2 l 750 ml = 6 l 1,250 ml = 7 l 250 ml. A rope of 5 m - cut 1 m 35 cm → remaining?
Practice
Convert: 4.5 km to m - 3,400 g to kg - 2,500 ml to l. Add: 3 km 450 m + 2 km 750 m. Subtract: 5 kg - 2 kg 350 g.
Word Problems
A shopkeeper has 5 kg 250 g of sugar. He sells 3 kg 700 g. How much is left?
Three pipes are 2 m 35 cm, 1 m 80 cm and 3 m 45 cm. What is their total length?
Measurement Tip: Always convert to the same unit before adding or subtracting! This prevents the most common mistake.
Day 27 - TueTime & Calendar
Concept
Units: 60 sec=1 min - 60 min=1 hour - 24 hr=1 day - 7 days=1 week - 28/29/30/31 days=1 month - 12 months=1 year - 365/366 days=1 year. 12-hour vs 24-hour clock. AM vs PM. Elapsed time = End time - Start time.
Examples
A film starts at 2:45 PM and ends at 5:10 PM. Duration = 2 hr 25 min. Convert 3:30 PM to 24-hour clock = 15:30. How many days from 15 March to 10 April?
Practice
Convert: 3:20 PM to 24-hr - 14:45 to 12-hr. Elapsed time: starts 9:15 AM ends 11:40 AM. Days between 20 May and 5 July.

Data = collected information. Tally marks: IIII (4), then ̶I̶I̶I̶I (5 = one bundle). Frequency table. Bar graph: X-axis (categories), Y-axis (frequency), equal spacing, equal width bars, title and labels. Reading and interpreting graphs.
Examples
Nandika surveys 20 friends about favourite subjects. Organise in tally table. Draw bar graph with scale 1 cm = 2 students. Answer questions from the graph: Which subject is most popular? Least?
Practice
Given data - make tally table and bar graph. Answer 5 questions from the graph: most, least, total, difference, "how many more".
Real Survey
Nandika surveys her family: favourite fruit, favourite colour or favourite season. Collect data, make tally marks, draw bar graph and present findings!
Data handling is used by scientists, doctors, businesses and governments. Nandika is learning to read the world through numbers!
