Timeline

Week 1 & 2 (13 June - 26 June)

I started working with 10's complement. In the first sub-activity, we have to place the 10's complement of the given number in the empty place. This sub-activity consists of 3 levels. In the first week, I added the all required components and added required attributes to them, such as color and border shape. and created a separate component, "NumberCard," so it could be used multiple times, and these cards were rendered in numberContainer (pink box left side) using ListModel, and their size was found by "Core.fitItems." In the second week, I created another component, "AnswerContainer," as all the numberCards will appear inside the answer container. Completed the visual appearance of the activity.

Activity progress

Week 3 & 4 (27 June - 10 July)

I implemented the functioning of sub-activity 1. The user can replace the "question mark" with a number by first clicking on the number and then the question mark. Initially, the display for three answerContainer was hard-coded, so I improved them by using ListModel. Added the reload button. During this time I also initialized the sub-activity 2, Swapping 10's complements. There is a separate card and cardContainer. The cards are inside the container in horizontal ListView. I also Implemented the dataset up to 3 levels in sub-activity 1.

Activity Progress

Week 5 & 6 (11 July - 24 July)

Added level 1 and 2 to sub-activity 2. Level 1 contains 4 numbers and 5 numbers respectively to swap. The symbols and numbers inside the container are the same cards with different properties visually and only the number is clickable. And the selected number in enlarged a little bit as compared to others to provide the assurance of current selected card. Made the "okButton" working. The click on it will validate the answers.

Week 7 & 8 (25 July - 7 August)

By this time activity 1, had a basic structure and working functionality to it. After that, we added sublevels to every level. The user needs to successfully answer all the sublevels in order to proceed to the next level. And to help the user visualize how many sublevels are left, we added the sublevel counter. In sub-activity 2, added level 3, which has 3 pairs to form ten's complement. In total this level has 6 numbers and the user needs to swap the numbers in a row to make the first-second, third-forth, and fifth-sixth numbers tens's complement each other. In sub-activity 3, added level 2, and there are two equations to solve. And the values loading in the equations were also made random so the user gets a new random set of questions to answer every time the activity is played.
