January 4th to 6th - Week 1

We worked for only three days in the first week of the second term.

In UOI, we continued with the unit on civilizations. The students did Map work and located the different continents and the states of India on a world and an Indian map respectively. The students did the progressive mind maps and analyzed the meaning of a 'civilization' using the story boards. We began with the Indus Valley Civilization. Students were divided into groups based on the different aspects of a civilization: Culture, systems, inventions and discoveries and other interesting facts.

In English, we continued with story writing. The students wrote the stories for their story boards in their writing books. We also looked into direct and indirect speech and their interconversion.

In math, we first had revision for the mid term assessment. All the concepts covered in the first term were revised in the class. We then began with the unit on fractions. We had the pre unit assessment. The students were asked to estimate fractions on straight lines. They were then asked to calculate the correct answer and find the errors. We also had some extension activities.

As we had a break today and we have a weekend ahead, here is some math homework for the students. This will help them with the Math mid term assessment to be held on Monday. The concept of BODMAS needed some extra practice and hence more problems on this concept have been given. Part 1 and 2 needs to be done by all, part 3 and 4 are extension. All the problems can be solve in the math notebook or can be copied and printed out.


1. (740 ÷ 5) - (2 + 3)
2. 732 ÷ 6 × 1 + 4
3. (880 ÷ 5) + 5 - 2
4. (9 + 1 × 5 + 2) ÷ (8 × 1)
5. 624 ÷ 8 × 2 + 1 × 3 - 4
6. (234 ÷ 2) + (944 ÷ 8)
7.  8 + 306 ÷ 9
9. (180 ÷ 3) × (1 + 1) × 2
10. (6 + 5 × 2 + 2) ÷ (8 - 2 × 1)
11. (385 ÷ 5) - (3 + 2 + 5 × 4)
12. 868 ÷ 7 × 4 + 2 + 3

PART 2 (For all):


1. Tyler and Christina are playing a game in which each player either wins, loses, or draws (ties) at each turn. The winner of a turn is awarded 5 points, and the loser loses 5 points. If it is a draw, 0 points are awarded. For the first eight rounds Tyler had the following results: lose, win, lose, win, win, lose, win, draw. What was Christina's point total for the rounds?

2. During an electronics experiment in your laboratory, you measure the voltage at terminal A on your newly designed circuit. You measure -12 volts. You check the same terminal after making a small change to the circuit and this time you measure -18 volts. What was the voltage difference between the two readings? 

4. Mr. Waffle is a circus clown. He starts the day with sixty-eight pieces of candy. At the end of the day he has given away 383 pieces of candy. How many more pieces of candy did he have to get, in addition to his original sixty-eight, to be able to give away that many pieces?
