class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Matiko is <strong>an online exercise bank, sorted by class, by chapter and then by section.<\/strong> The student types their result directly, the site tells them if it is right, and then proposes a detailed step-by-step correction. Everything happens in the browser, on computer as well as on smartphone. The interface was first designed for the telephone.<\/p>\n<p>Behind the site, there is no school editor. Its creator, engineer and independent project manager, explained to me that he started it after accompanying his two daughters, one in middle school, the other in high school, in their revisions, because he did not find training resources that suited him. He is not a teacher and he says it frankly.<\/p>\n<p>In the landscape, Matiko is somewhere between the large corrected PDF banks and the solvers who spit out the answer as soon as the statement was photographed (I had reviewed several of them in <a href=\"https:\/\/outilstice.com\/outils-pour-resoudre-des-problemes-mathematiques\/\" target=\"_blank\">this overview of tools to solve math problems<\/a>). Here on Matiko, the student has to look for himself, and the site only intervenes if he gets stuck.<\/p>\n<p>&nbsp;<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter size-large wp-image-16737\" src=\"https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-1024x397.png\" alt=\"corrected math exercises\" width=\"720\" height=\"279\" srcset=\"https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-1024x397.png 1024w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-300x116.png 300w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-768x298.png 768w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-1536x595.png 1536w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-2048x794.png 2048w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.39.21@2x-18x7.png 18w\" sizes=\"auto, (max-width: 720px) 100vw, 720px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Un_exercice_corrige_pas_a_pas_avec_des_indices_a_la_demande\"><\/span>A corrected exercise step by step, with indices on demand<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Un_rappel_de_cours_avant_de_se_lancer\"><\/span>A course reminder before you start<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Each section opens with an \u2018Essential part of the course\u2019 sheet: two or three concepts, each with a property, a method and an example. I opened the one on the addition and subtraction of relatives in fifth grade. It\u2019s short, clean, and it\u2019s enough to put the rule first before attacking.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Trois_niveaux_de_difficulte\"><\/span>Three levels of difficulty<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Exercises are labelled Standard, Advanced or Challenge, with a filter to display only one level. In the same section, we move from a simple calculation of the sum to a submarine problem that chained four movements before returning to its station at -12.5 m (I did not know that we parked the submarines so close to the surface, but let\u2019s pass). There are many contextualised statements, and this is rather good news.<\/p>\n<h3><span class=\"ez-toc-section\" id=\"Une_correction_qui_montre_la_methode\"><\/span>A correction that shows the method<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The student works on the draft, enters his answer and clicks on \u2018Check\u2019. If he blocks, he asks for a clue. The correction then details the reasoning in stages, with two inserts that I found really well seen: \u2018Key method\u2019 and \u2018Trap to avoid\u2019. In a first specialty exercise dedicated to the second degree, the trap reported is the confusion between the abscissa of the summit and the value of the extremum. Exactly the error found in the copies.<\/p>\n<p>At the end, the student indicates whether he\/she has understood or whether he\/she is still \"bug\". All this is covered with experience points, ranks and series of consecutive days. A fairly discreet layer of play, to which some students will be sensitive.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-16738\" src=\"https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x-1024x871.png\" alt=\"Corrected Mathematical Exercise\" width=\"636\" height=\"541\" srcset=\"https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x-1024x871.png 1024w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x-300x255.png 300w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x-768x653.png 768w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x-1536x1306.png 1536w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x-14x12.png 14w, https:\/\/outilstice.com\/wp-content\/uploads\/2026\/10\/CleanShot-2026-10-16-at-17.41.03@2x.png 1766w\" sizes=\"auto, (max-width: 636px) 100vw, 636px\" \/><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Ce_que_vous_pouvez_en_faire_avec_vos_eleves\"><\/span>What you can do with your students<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The most useful detail for a teacher is not highlighted on the website: <strong>each exercise has its own address.<\/strong> You can therefore copy the link of a specific exercise, or of an entire section, and place it in the ENT\u2019s textbook, in Pronote or in a QR code projected in the table.<\/p>\n<ul>\n<li><strong>To differentiate<\/strong> : A single section link, and each student chooses their level. The most comfortable go to the Challenge exercises, the others stay on Standard without feeling left out.<\/li>\n<li><strong>Before an inspection<\/strong> : three or four targeted exercises, with a simple instruction. The process is written on the notebook before entering the result.<\/li>\n<li><strong>Help with homework or personalised support<\/strong> : The course sheet and the clues allow the student to move forward alone while you are travelling.<\/li>\n<li><strong>For students without a computer at home<\/strong> : a smartphone is enough, without an application to install.<\/li>\n<\/ul>\n<p>For a dys or allophone student, on the other hand, contextualised problems take quite a long time to read, and I have not seen statements read aloud. The course sheet, short and structured, compensates a little.<\/p>\n<p>In the senior year, Matiko covers specialty and expert math. To train on complete bac-type subjects, it will be necessary to complete it with another tool, for example: <a href=\"https:\/\/outilstice.com\/maths-forge-sujets-bac-maths-personnalises\/\" target=\"_blank\">Maths Forge and his personalized baccalaureate subjects<\/a>.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"De_la_5e_a_la_terminale_avec_un_catalogue_encore_en_chantier\"><\/span>From the 5th to the terminal, with a catalogue still under construction<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The proposed levels: 5th, 4th, 3rd, second, first specialty, final specialty and expert math. No 6th for the moment, no complementary math or professional path, to my knowledge. For computational automations at the beginning of college, <a href=\"https:\/\/outilstice.com\/calculatice-jeux-mathematiques-entrainement-calcul-mental\/\" target=\"_blank\">Calculatice<\/a> remains a good lead.<\/p>\n<p>The site announces more than 200 exercises per level, and the presentation sent by the creator evokes a target of 300, covering the 2026-2027 programs.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Matiko_est-il_vraiment_gratuit_et_sans_inscription\"><\/span>Is Matiko really free and without registration?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Yes for the most part. No subscription, no account: the student arrives and starts. According to the privacy policy, progress (points, series, successful exercises) is recorded only in the browser and is never transmitted to the site\u2019s servers.<\/p>\n<p>That said, on the first visit, a banner offers to accept or refuse audience measurement cookies and advertisements, served in particular by Google AdSense. At the moment, the site is perfectly clean and does not offer any advertising. It will be necessary to monitor whether this changes in the future.<\/p>\n<p>Some other things to know. The site is hosted by Render, in the United States, behind Cloudflare. Without taking into account, you have no dashboard, so no way of knowing who did what. On a shared post at the CDI, a student\u2019s progress will remain visible for the next one (a \u2018Reset\u2019 link exists at the bottom of the page). Finally, the presentation speaks of a \u2018free\u2019 resource, but the legal notices reserve all the rights to the exercises: sharing the links is not a problem, copying the statements in your own sheets implies asking for authorisation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Ce_que_jaime_ce_que_jaime_moins\"><\/span>What I like, what I like less<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<h3><span class=\"ez-toc-section\" id=\"Ce_que_jaime\"><\/span>What I like<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>No account, neither for you nor for the students.<\/li>\n<li>The \u2018Key method\u2019 and \u2018Trap to avoid\u2019 inserts, which resemble what is said when correcting the table.<\/li>\n<li>The clues, which push to look before looking at the correction.<\/li>\n<li>One link per exercise, easy to drag into the ENT.<\/li>\n<li>A very successful interface really comfortable on smartphone.<\/li>\n<\/ul>\n<h3><span class=\"ez-toc-section\" id=\"Ce_que_jaime_moins\"><\/span>What I like less<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<ul>\n<li>No follow-up for the teacher, and that, frankly, is a lack for classroom use.
