A BundleBundle BBBoard shows that
6*7 = (B-4)*(B-3) = (10 – 4 – 3)*B + 4*3 = 3B12 = 4B2 = 42
6*7 = 6*½B2 = 3B12 = 4B2 = 42

Introduction
Looking at four fingers bundled in twos, an educated person sees four fingers, the essence. But, as uneducated before school, children see what exists, bundles of twos in space, and two of them when counted in time. We thus observe the existence of two kinds of mathematics: ‘half-matics’ that teach only the counting-numbers, 1, 2, 3, etc.; and ‘full-matics’ that connects counting-numbers in time with bundle-numbers in space 1s, 2s, 3s, etc. to teach the child’s own numbers with bundle-units as 2 3s visible and tangible on a ten-by-ten BundleBundleBoard. We may now ask how mathematics may be taught to children if using their own two-dimensional numbers with bundle-units instead of the school’s one-dimensional line-numbers without units. In other words, we may ask how children may learn mathematics by meeting existence before essence to use the two core concepts of Existentialism holding that existence must precede essence.
Counting outside Totals in Bundles then must precede adding them inside. In this ‘Bundle-math’ approach, mathematical concepts are re-rooted in outside existing examples instead of being defined as examples itself inside. Now tens, hundreds and thousands become bundles, bundle-bundles, and bundle-bundle-bundles, as does 2, 4 and 8 when counting in twos instead.
Bundle-counting, one-dimensional lines on a ruler are replaced by two-dimensional rectangles on a BBBoard, containing the outside existing subjects that is linked to inside essence predicates in a number-language sentence as in a word-language sentence. Here units are always included in counting sequences as 0Bundle1, 0B2, …, 1B0. Here digits become icons with as many sticks as they represent. Here also operations become icons created in the counting process. An outside Total may be split by pulling away a Bundle, using a rope as an icon for subtraction. Pulled back, the total is restored in a Reunite-formula, T = (T – B) + B, using a double-rope as an icon for pulling back. Or, the outside Total may be counted in Bundles by pushing away Bundles, using a broom as an icon for division. Pushed back, the total is restored in a Recount-formula, T = (T/B) x B, using a lift as an icon for pushing back. The Recount formula is used all over STEM to change units.
Recounting from tens to icons, the equation, u2 = 8, together with another basic equation, u+2 = 8, are solved by recounting and reuniting, both moving numbers to ‘opposite side with opposite sign’: u2 = 8 = (8/2)x2, so u = 8/2, and, u + 2 = 8 = (8 – 2) + 2, so u = 8 – 2.
Recounting from icons to tens leads to early algebra when including the Bundle-unit. Then 6*7 becomes (B-4) * (B-3) placed on a BBBoard and found by pulling-away the top 4B and side 3B, and adding the 43 pulled away twice. Or by writing 67 = 6* ½B2 = 3B12 = 4B2. And, bundle-bundles squares allow rectangular stacks to be recounted in squares with the square root as the side.
Recounting in physical units creates per-numbers as 4$/5kg bridging the units by recounting: 20kg = (20/5)5kg = (20/5)4$ = 16$. With like units, per-numbers become fractions: 4$/5$ = 4/5.
Recounting the sides in a stack halved by its diagonal leads to trigonometry before geometry.
Recounting now is followed by reuniting (called ‘Algebra’ in Arabic). Stacks may add on-top after recounting has made the units like, or next-to as areas, i.e., as integral calculus (or differential calculus if reversed), also used to add per-numbers and fractions that must be multiplied to unit-numbers to add. Squares add as the square formed by their mutual Bottom-Top line.
Units create an ‘Algebra Square’ to reunite our four number-types. Add and multiply unite unlike and like unit-numbers, where integrate and power unite unlike and like per-numbers. That are split by subtraction, division, differentiation, and the factor-finding root or the factor-counting logarithm.
Counting before adding thus gave us a number-language to tell inside number-tales about outside totals using the same three genres, fact and fiction and fake, as the word-language uses.
Can mathematics be decolonized? Well of course, since mathematics is a socially constructed essence that will always be a colonization of the natural existence it came from and reduces.

Presentation Category at EARCOME9: Special Sharing Groups (SSG). Title of Paper: CAN A DECOLONIZED MATHEMATICS SECURE NUMERACY FOR ALL?
Announcement: This proposal tackles an urgently needed conversation in mathematics education by challenging deeply ingrained assumptions about number systems and arithmetic instruction and proposing a truly decolonized approach that foregrounds learners’ intuitive “bundle‑number” language. Its strength lies in weaving together a compelling theoretical critique—drawing on Habermas’s colonization concept and rich philosophical underpinnings—with concrete instructional innovations like the Algebra Square that reframe operations as intuitive spatial and bundling processes. By aligning this reconceptualization directly with SDG 4’s numeracy targets and illustrating how multiplication‑centered reasoning better reflects real‑world number use, the paper promises to make a bold and impactful contribution to both research and practice. We look forward to seeing how this work can reshape numeracy instruction and foster truly inclusive mathematical literacy for all.

Matematik: MatemaTisme, eller MangeMatik med barnets 2D BundtBundtTal på etBBBræt?

Matematik blir så let hvis Mange mestres først med MangeMatik. MATERIALE, se senere.

MangeMatik respekterer, at MANGE beskrives med barnets egne BundtBundt-tal med enheder – i stedet for at få påtvunget falsk WOKE-identitet som linjetal uden enheder, der blir matematisme ved at påstå, at 2+1 er 3 altid, til trods for at 2dage+1uge er 9dage.

MangeMatik ses ved at spørge en 3-årig “Hvor mange år næste gang?” Svaret er 4, med 4 fingre vist. Men holdt sammen 2 og 2, indvender barnet “Det er ikke 4, det er 2 2ere.” Barnet ser således, hvad der findes i rum og tid, bundter af 2ere i rummet, og 2 af dem i tid, når de tælles. Så det, der eksisterer, er totaler, der kan optælles til (gen)forening (algebra på arabisk) i rum og tid, som fx 2B1 2ere.

MangeMatik bygger på filosofien eksistentialisme, der anbefaler, at eksistens går forud for essens, der ellers vil kolonisere eksistensen. Det eksternt eksisterende går altså forud for interne ’essens-regimer’ som bør dekonstrueres & demodeleres så eksistensen afkoloniseres

BundtTal med enheder: 8, 0B8, 1B-2, eller 1B0 8ere. Og 87, 8B7, 9B-3.

Forord
Mange er det første vi møder, overalt i rum og tid, som fingre og som åndedrag, osv. Og Mange er indlejret i sproget som ental og flertal, som bundt-tal og tælle-tal, og som styk-tal og per-tal.
Hvor barnet har sin egen naturlige forståelse af Mange, har skolen en helt anden kunstig forståelse af Mange. Som kaldes matematik, men som i stedet er en selvskabt kunstfærdig ’matematisme’ uden enheder, altid sandt inde i skolen, men sjældent uden for skolen, hvor der altid er enheder.
Men hvorfor skal skolens kunstige intelligens påtvinges barnet, så det mister sin naturlige intelligens?
Så dette er fortællingen om barnets eget tal-sprog, der bruger fleksible bundt-tal med enheder i stedet for skolens stive linje-tal uden enheder.
At et barn har sit eget tal-sprog ses ved at spørge en 3årig ”Hvor mange år bliver du næste gang?”. Svaret kommer straks med fire finger løftet i vejret. Men barnet protesterer, hvis man viser fire fingre samlet to og to: ”Det er ikke fire, det er 2 toere.”
Barnet ser, hvad der eksisterer i rum og tid, bundter med to i rum, optalt til to i tid. Så barnet skelner mellem eksistens og essens. < fortsættes i e-bogen>

Calculus across disciplines

How do biologists, chemists, economists, engineers and physicists understand and use calculus concepts in their disciplines? And what does that imply for the teaching and learning calculus in their disciplines? This conference seeks to explore these complex questions by bringing specialists from these disciplines together with mathematics educators.

NORMA 24 – Interplay between research and teaching practice in mathematics education


NORMA 24, The Tenth Nordic Conference on Mathematics Education will take place in Denmark from the 4th to the 7th of June 2024 at Aarhus University, Campus Emdrup in Copenhagen.

The NORMA conferences are organized in collaboration with NoRME​- the Nordic Society for Research in Mathematics Education, https://sites.google.com/view/norme/home, NoRME is open for membership from national societies for research in mathematics education in the Nordic and Baltic countries.

The NORMA conferences offer forum for discussions and constructive interactions among researchers, teachers, teacher educators, graduate students and others interested in mathematics education research in the Nordic context. NORMA are small-scale conferences that emphasize interaction between participants and interplay between scientific and social activities.

Apparently, we have 2 Mathematics Paradigms, one without Units, and one With Units

• an inside ‘no-unit-math’ paradigm, where 1 plus 2 is 3 always despite 1week + 2days is 9days, and
• an outside ‘unit-math’ paradigm, where 1 plus 2 depends on the units

The ‘unit-math’ paradigm builds on the philosophy, EXISTENTIALISM, where EXISTENCE precedes ESSENCE
So, unit-math describes real existence, and neglects institutionalized essence

The outside, ‘unit-math’ paradigm, provides the same mathematics, as the inside, ‘no-unit-math’ paradigm, only in a different order. And, the ‘unit-math’ paradigm, avoids the inside paradigm’s ‘mathema-tism’, with its falsifiable, addition-claims.

So, to become a full science, mathematics should leave, its 1 plus 2 is 3, ‘no-unit-math’ greenhouse, and accept that, of course, numbers cannot add, without units.

It should teach the outside ‘counting-before-adding’, ‘unit-math’, paradigm, where Numbers and operations are icons, linked directly to existing things, and actions
