4 days ago · Financial modelling is a powerful decision-making and due diligence tool. Here’s why almost every financial professional uses at some point during their career: Scenario analysis and data-backed decisions: Models allow you to forecast financial performance and stress-test your numbers under various scenarios.

The three steps of an accounting information system are input, processing, and output. Data is the raw ingredient used in these processes. Some of the data may be obtained from a source document, and other data is obtained from the database where it had previously been stored.

RUCSAC is an acronym that has been popular for teachers to help children unpick word problems. Read the question carefully Underline keywords in the question Choose the required operation(s) Solve the problem Answer the problem Checkyour answer Many teachers have fallen out of love with RUCSAC, particularly because underlining the keywords is quite...
Take the following word problem: If Jamal has three apples and Ruth has two apples, how many apples do they have altogether? To help children solve this problem, we could use a bar model and mathematical equipment. You could use either real apples, counters, cubes, or similar, as represented in the solution below. Shown in the Number Stacks video l...
We are presented with the same word problem, but this time, the bar model itself carries the pictorial nature of the solution. Both parts hold numbers and the total bar holds also a number by itself, without the familiar unit of measurement (apples).
Finally, with the same word problem in mind, we can see how using the bar model supports children in progressing to using abstract number sentences, with the + and = symbols employed in this scenario.
If a picture is worth a thousand words, this wonderful video by Number Stacksis worth at least a million words in demonstrating best practices in using bar models in a concrete/pictorial manner in KS2. In this instance, focusing on fractions of amounts.
Ultimately, bar models should lower the cognitive load of children. Using bar models should allow them to work through problems more quickly, not slow them down. If a child is working out how many squares in their grid/square paper exercise book they need to use to draw the bar model, then this thinking is slowing them down. The only time you want ...
Some schools and schemes will advocate for one type of bar model usage over another. Some might exclusively use bar models like those shown on the left of the slide above, while others might favour bars curly brackets, and double arrow-headed lines, as on the right-hand side of the slide. There is certainly strength in having a consistent and prefe...
The use of part-part-whole bars versus bars with curly brackets is particularly apparent when performing subtraction calculations. Here, the following word problem has been posed: “If Ahmed and Eve have 8 oranges in total and Ahmed has five oranges, how many oranges does Eve have?” So, using our bar model flow chart, we can draw up a part-part-whol...
Bar models can be used for each of the four operations in KS2 (as well as multi-step, mixed operation problems, and more). We have provided a similar subtraction word problem. Now the complexity has increased, as we are dealing with three-digit numbers and a unit of measurement, too. Ahmed has to walk 453m to get to school. Eve has to walk 689m to ...
Bar models can be used to help solve addition calculations for all primary year groups. Once more, we can use the bar model flow chart to help draw the bar model. The word problem is: James has 237 tokens. Yasmin has 342 tokens. In total, how many tokens do the two friends have? Do we know the total? No. Are the parts equal? No, so we know it will ...
Bar Modelling. The bar can be a valuable representation to enable students to represent problems in such a way that the mathematical structure is exposed. This enables students to ‘see’ the problem clearly and to then recognise the strategy they need to solve the problem. NCETM. Avoid the common mistakes!
Bar modelling is used to help understand how to solve problems in various mathematical topics including ratio, proportion, and equations.
