The world's best football player engages in rigorous training, practicing skills repeatedly to prepare for the big game. While the specific actions rehearsed during these exercises are rarely needed in the match, the very process of performing these drills enhances their overall prowess as a top player. more...
Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

I've been trying to grasp the concept of differential forms, which I have been encountering while studying the text "Geometric Measure Theory" by Frank Morgan. Unfortunately the explanation is very sparse and while the internet contains many definitions, I have a hard time getting the bigger picture from just reading them. Are there any lists of exercises that I could do to assist my understanding by just working with them?
Maybe you will find useful the notes by Sjamaar - "Manifolds and Differential Forms" which can be downloaded for free at his website. The explanation is geometrically motivated and straightforward from the ground up, and it contains lots of doable exercises and explicit detailed examples which may help you grasp everything you need to know and more. Donu Arapura has a nice elementary summary of the concepts and uses of differential forms in his notes Arapura - "Introduction to differential forms" freely downloadable too.
As a conceptual complement, a very interesting book geared toward theoretical physics applications is Baez/Muniain - "Gauge Fields, Knots and Gravity" where the meaning and extensive use of covectors and differential forms in general is used as a primary tool to formulate physical theories in geometric terms.
Using the general framework to rederive classical results should be a good exercise and let you see how the general framework relates to what you already know. Here are two exercises I think will be enlightening.
Show that the de Rham complexes of $\mathbbR^2$ and $\mathbbR^3$ are isomorphic to $$0\rightarrow C^\infty(\mathbbR^2,\mathbbR)\stackrel\textgrad\longrightarrowC^\infty(\mathbbR^2,\mathbbR^2)\stackrel\textrot\longrightarrowC^\infty(\mathbbR^2,\mathbbR)\rightarrow 0$$and$$0\rightarrow C^\infty(\mathbbR^3,\mathbbR)\stackrel\textgrad\longrightarrowC^\infty(\mathbbR^3,\mathbbR^3)\stackrel\textcurl\longrightarrowC^\infty(\mathbbR^3,\mathbbR^3)\stackrel\textdiv\longrightarrowC^\infty(\mathbbR^3,\mathbbR)\rightarrow 0$$respectively.
I would recommend Do Carmo's "Differential Forms and Applications". That's where I first learned differential form. It explains differential form very clearly and it contains exercises for each chapter. I benefit a lot by doing the exercises in the book.
The PISA 2022 mathematics framework defines the theoretical underpinnings of the PISA mathematics assessment based on the fundamental concept of mathematical literacy, relating mathematical reasoning and three processes of the problem-solving (mathematical modelling) cycle. The framework describes how mathematical content knowledge is organized into four content categories. It also describes four categories of contexts in which students will face mathematical challenges.
The PISA assessment measures how effectively countries are preparing students to use mathematics in every aspect of their personal, civic, and professional lives, as part of their constructive, engaged, and reflective 21st Century citizenship.
PISA 2022 aims to consider mathematics in a rapidly changing world driven by new technologies and trends in which citizens are creative and engaged, making non-routine judgments for themselves and the society in which they live. This brings into focus the ability to reason mathematically, which has always been a part of the PISA framework. This technology change is also creating the need for students to understand those computational thinking concepts that are part of mathematical literacy. Finally, the framework recognizes that improved computer-based assessment is available to most students within PISA.
In mathematics, students learn that, with proper reasoning and assumptions, they can arrive at results that they can fully trust to be true in a wide variety of real-life contexts. It is also important that these conclusions are impartial, without any need for validation by an external authority.
This fundamental and ancient concept of quantity is conceptualized in mathematics by the concept of number systems and the basic algebraic properties that these systems employ. The overwhelming universality of those systems makes them essential for mathematical literacy.
It is also important to understand matters of representation(as symbols involving numerals, as points on a number line, or as geometric quantities) and how to move between them;the ways in which these representations are affected by number systems;and the ways in which algebraic properties of these systems are relevant for operating within the systems.
The fundamental ideas of mathematics have arisen from human experience in the world and the need to provide coherence, order, and predictability to that experience. Many mathematical objects model reality, or at least reflect aspects of reality in some way. Abstraction involves deliberately and selectively attending to structural similarities between objects and constructing relationships between those objects based on these similarities. In school mathematics, abstraction forms relationships between concrete objects, symbolic representations, and operations including algorithms and mental models.
Structure is intimately related to symbolic representation. The use of symbols is powerful, but only if they retain meaning for the symbolizer, rather than becoming meaningless objects to be rearranged on a page. Seeing structure is a way of finding and remembering the meaning of an abstract representation. Being able to see structure is an important conceptual aid to purely procedural knowledge.
A robust sense of mathematical structure also supports modelling.When the objects under study are not abstract mathematical objects, but rather objects from the real world to be modelled by mathematics, then mathematical structure can guide the modelling.Students can also impose structure on non - mathematical objects in order to make them subject to mathematical analysis.
Relationships between quantities can be expressed with equations, graphs, tables, or verbal descriptions. An important step in learning is to extract from these the notion of a function itself, as an abstract object of which these are representations.
The word formulate in the mathematical literacy definition refers to the ability of individuals to recognize and identify opportunities to use mathematics and then provide mathematical structure to a problem presented in some contextualized form. In the process of formulating situations mathematically, individuals determine where they can extract the essential mathematics to analyze, set up, and solve the problem. They translate from a real-world setting to the domain of mathematics and provide the real-world problem with mathematical structure, representations, and specificity. They reason about and make sense of constraints and assumptions in the problem. Specifically, this process of formulating situations mathematically includes activities such as the following:
The word employ in the mathematical literacy definition refers to the ability of individuals to apply mathematical concepts, facts, procedures, and reasoning to solve mathematically formulated problems to obtain mathematical conclusions. In the process of employing mathematical concepts, facts, procedures, and reasoning to solve problems, individuals perform the mathematical procedures needed to derive results and find a mathematical solution. They work on a model of the problem situation, establish regularities, identify connections between mathematical entities, and create mathematical arguments. Specifically, this process of employing mathematical concepts, facts, procedures, and reasoning includes activities such as:
The word interpret (and evaluate) used in the mathematical literacy definition focuses on the ability of individuals to reflect upon mathematical solutions, results, or conclusions and interpret them in the context of the real-life problem that initiated the process. This involves translating mathematical solutions or reasoning back into the context of the problem and determining whether the results are reasonable and make sense in the context of the problem.
