School Time Table Software
Bradley Zweig
At Timestables.com you can easily practice all of your tables. The arithmetic problems are clear and simple so you can immediately get started on practicing your tables. Select one of the multiplication table you wish to practice from the list below and show what you can do on the speed test or printout great worksheets.
Choose the table you want to practice from the following. First you can practice the multiplication facts in sequence and once you have got the hang of that you can practice all the sums in random order for each table. If you have forgotten any answers, just go back to the 'all tables in sequence' page and practice them again thoroughly before trying again.
Once you have got the hang of a number of tables you can select the speed test and choose the tables you want to practice getting quicker at. If you make a mistake, you came see what the right answer is at the end of the test. This will help you learn all of your tables. The speed test is good practice for getting your tables diploma. On the tables diploma the questions are a bit quicker than on the speed test, but if you get all of them right you will get your tables diploma. There are two tables diplomas. The little diploma is made up of 30 questions. Your little diploma shows you can do the 1,2,3,4,5 and 10 times tables. For the big tables diploma you are given 40 questions which include all the tables from 1 to 12.
Learn the multiplication tables in an interactive way with the free math multiplication learning games for 2nd, 3rd, 4th and 5th grade. The game element in the times tables games make it even more fun learn.
Here you can find additional information about practicing multiplication tables at primary school. The 1 times table, 2 times table, 3 times table, 4 times table, 5 times table and 10 times table are the first times tables to be learned. The 6 times table, 7 times table, 8 times table, 9 times table, 11 times table, 12 times table and of course all the tables in random order are the next step.
Not every child finds it easy to learn all the tables, so it is a good idea to keep on practicing them regularly after you learned them. There are a few tricks which make it easier to learn the tables and continue to master them, such as putting the smallest number first, which makes it easier for many children to answer correctly. For example 4 x 9 is easier to work out than 9 x 4. Switching the multiplication sum around makes it easier to answer. What also often helps is to use the tables you know well for answering the sums in the more difficult tables. One example of this is 6 x 7, which is often said to be tricky. If you do 5 x 7 first and then add 1 x 7 it is suddenly easier to answer. You can do this the other way round too. For instance with 4 x 7 you can do 5 x 7 first then subtract 1 x 7.
Why do we put so much effort into learning tables? Well, the multiplication tables keep on coming up in the next primary school years and even when you're at secondary school. You don't see them as tables, but as part of bigger mathematical problems. And it isn't only at school, but in your everyday life it is useful to know your times tables well so you can quickly work things out, for instance when you are buying or selling vegetables on the market.

My questions:
1) Is it right to look at it as an assignment problem with multiple constraints?
2) Which algorithm should I use? (Hungarian algorithm?)
3) Should I start by getting the whole set of constraints at one go, and then generate the table, or should it be done in intermediate steps?
You've picked a doozy of a problem to start with. Scheduling optimization like this is NP complete. There are a ton of papers on how to deal with problems like this the class of problem is known as constrain satisfaction. You can perform an exhaustive search which is easiest but is also very time consuming, if you have more than a handful of classes it won't work. You might take a look at solver foundation which is a suite of tool for .net for solving these sorts of things. Scott Hanselman did a podcast about it here =209 and you can find more about it here If you fancy doing it yourself try looking at GSAT or otherwise some of these evolutionary algorithms look interesting -3-540-48582-7.
I'll reiterate that the most suitable solution technique for scheduling problems like this are in the area of constraint programming. While other optimization techniques are OK for small problems, formulation often is painful for some constraints. Consider all of the integer variables you have to create for some simple constraints. Because the problem often requires a bunch of feasible schedules (or to determine infeasibility) rather than an optimal solution, CP is the preferred approach since that's what it's designed to do. Most other approaches require a user to "force" an optimality condition on the problem where one doesn't really exist.
You can create any number of schedules and timetables, easily switch between them, manage and customize them.

No problem! You can help them by sending them your schedule using a code, a link to the web version or through other convenient options.
A school timetable is a calendar that coordinates students and teachers within the classrooms and time periods of the school day. Other factors include the class subjects and the type of classrooms available (for example, science laboratories).
A school timetable consists of a list of the complete set of offered courses, as well as the time and place of each course offered. The purposes of the school timetable are to inform teachers when and where they teach each course, and to enable students to enroll in a subset of courses without schedule conflicts.[1]
Prior to the introduction of operations research and management science methodologies, school timetables had to be generated by hand. Hoshino and Fabris wrote, "As many school administrators know, creating a timetable is incredibly difficult, requiring the careful balance of numerous requirements (hard constraints) and preferences (soft constraints). When timetables are constructed by hand, the process is often 10% mathematics and 90% politics,[2] leading to errors, inefficiencies, and resentment among teachers and students."[1]
...involve additional constraints that must be satisfied, further increasing the complexity of the STP (school timetable problem).[3] These variations include event constraints (e.g. Course X must be scheduled before Course Y), and resource constraints (e.g. scheduling only one lab-based course in any timeslot). At large universities, there are additional constraints that must be considered, such as taking into account the time students need to walk from one end of the campus to the other.[1]
Since the 1970s, researchers have developed computerized solutions to manage the complex constraints involved in building school timetables.[1] In 1976, for example, Gunther Schmidt and Thomas Strhlein formalized the STP with an iterative algorithm using logical matrices and hypergraphs.[4]
High school timetables are quite different from university timetables. The main difference is that in high schools, students have to be occupied and supervised every hour of the school day, or nearly every hour. Also, high school teachers generally have much higher teaching loads than is the case in universities. As a result, it is generally considered that university timetables involve more human judgement whereas high school timetabling is a more computationally intensive task (see the constraint satisfaction problem).[7]
