1 Packing Oranges - Numbers 21 to 30 (Pages 84-86)
🍊 Concept: Boxes of 10
Simran packs oranges in boxes. Each box holds exactly 10 oranges.
If she has 2 full boxes, that is 20 oranges.
If she has 2 full boxes and 1 loose orange, that is 21 (Twenty One).
This helps us understand that numbers in the 20s are made of "Two Tens" and some "Ones".
Page 86: Write 21 to 30 in the sequence.
The green boxes are the ones you need to fill in.
2 Numbers 31 to 50 (Page 87)
Let us count the number of flowers and the number of neem daatun (sticks).
Notice how 3 garlands/bundles of 10 makes 30. Then add loose ones (31, 32...). 4 bundles makes 40.
Fill in the missing numbers based on the pictures:
33
Thirty Three
34
Thirty Four
37
Thirty Seven
38
Thirty Eight

Page 88: B. Write the number on the number cards placed on the ginladi (Bead String).
The ginladi changes color every 10 beads (e.g., 10 yellow, 10 blue, 10 yellow, 10 blue...). Count carefully from the start!
Page 89: Count and write the numbers (Fill in the boxes).
i. 4 garlands of flowers + 5 loose flowers = 45
ii. 3 bundles of sticks + 8 loose sticks = 38
iii. 4 pencil cups (10 each) + 2 loose pencils = 42
4 Counting from 51 to 100 (Pages 90-93)
The pattern continues!
5 bundles = 50 (Fifty). 5 bundles + 1 stick = 51 (Fifty One)
6 bundles = 60 (Sixty). 6 bundles + 2 sticks = 62 (Sixty Two)
...all the way to 10 bundles = 100 (One Hundred)!
