Elementary students spend years trying to master arithmetic. Teens struggle with the shift to algebra and its use of variables. High-school students must face diverse challenges like geometry, more advanced algebra, and calculus. Even parents experience frustration as they struggle to recall and apply concepts they had mastered as young adults, rendering them incapable of providing math help for their children. Whether you need top Math tutors in Boston, Math tutors in Detroit, or top Math tutors in Dallas Fort Worth, working with a pro may take your studies to the next level. The truth is, everyone struggles with math at one time or another. Students, especially at the high-school level, have to balance challenging coursework with the demands of other courses and extracurricular activities. Illness and school absences can leave gaps in a student’s instruction that lead to confusion as more advanced material is presented. Certain concepts that are notoriously difficult to master, such as fractions and the basics of algebra, persist throughout high school courses, and if not mastered upon introduction, can hinder a student’s ability to learn new concepts in later courses. Even students confident in their math skills eventually find a course or concept incomprehensible as they reach advanced math classes. In other words, no matter what your age or ability, everyone eventually needs help with math. Varsity Tutors offers resources like free Math Diagnostic Tests to help with your self-paced study, or you may want to consider a Math tutor. Varsity Tutors is happy to offer free practice tests for all levels of math education. Students can take any one of hundreds of our tests that range from basic arithmetic to calculus. These tests are conveniently organized by course name (e.g. Algebra 1, Geometry, etc.) and concept (e.g. “How to graph a function”). Students can select specific concepts with which they are struggling or concepts that they are trying to master. Students can even use these concept-based practice tests to identify areas in which they may not have realized they were struggling. For instance, if a student is struggling with his or her Algebra 1 course, he or she can take practice tests based on broad algebra concepts such as equations and graphing and continue to practice in more specific subcategories of these concepts. In this way, students can more clearly differentiate between those areas that they fully understand and those that could use additional practice. Better yet, each question comes with a full written explanation. This allows students to not only see what they did wrong, but provides the student with step-by-step instructions on how to solve each problem. In addition to the Math Practice Tests and Math tutoring, you may also want to consider taking some of our Math Flashcards. Varsity Tutors’ Learning Tools also offer dozens of Full-Length Math Practice Tests. The longer format of the complete practice tests can help students track and work on their problem-solving pace and endurance. Just as on the results pages for the concept-specific practice tests, the results for these longer tests also include a variety of scoring metrics, detailed explanations of the correct answers, and links to more practice available through other Learning Tools. These free online Practice Tests can assist any student in creating a personalized mathematics review plan, too, as the results show which of the concepts they already understand and which concepts may need additional review. After reviewing the skills that need work, students can take another Full-Length Math Practice Test to check their progress and further refine their study plan. Once a student creates a Learning Tools account, they can also track their progress on all of their tests. Students can view their improvement as they begin getting more difficult questions correct or move on to more advanced concepts. They can also share their results with tutors and parents, or even their math teacher. Create a Varsity Tutors Learning Tools account today, and get started on a path to better understanding math!

Penggunaan Jari dalam Berhitung



Pada tulisan sebelumnya mengenai Jarimatika 99 telah dijelaskan mengapa menggunakan istilah tersebut. Pada tulisan kali ini kita akan membahas bagaimana cara menggunakan jari dalam berhitung dengan judul Penggunaan Jari dalam Berhitung dari 1 sampai 99. Perhatikan dua gambar berikut ini!


Pada gambar tersebut ditunjukkan bahwa tangan kanan mewakili bilangan dari 1 sampai 9 atau bilangan satuan sedangkan tangan kiri mewakili puluhan. Misalnya, bilangan 11 ditunjukkan dengan membuka jari telunjuk kiri dan jari telunjuk kanan, bilangan 12 ditunjukkan dengan membuka jari telunjuk kiri sedangkan pada tangan kanan membuka telunjuk dan jari tengah, begitu seterusnya. Sehingga pada kenyataannya 5 jari pada tangan kiri dan 5 jari pada tangan kanan menyatakan angka 99. Inilah yang saya maksud sebagai Jarimatika 99.

Perhitungan dengan jari ini hanya berlaku untuk penjumlahan, pengurangan dan perkalian sedangkan untuk pembagian hanya bentuk kebalikan dari perkalian saja. Operasi dasar ini disebut sebagai Operasi Dasar Matematika atau Anda bisa membaca Aritmatika Dasar.

Pentingnya menguasai logika, konsep, dan prinsip operasi adalah syarat awal bagi Anda untuk mempelajari bidang matematika lainnya. Seperti yang diungkapkan Gauss yang dijuluki sebagai Kalkulator Berjalan dan Pangeran Matematika mengatakan "Matematika adalah ratu ilmu pengetahuan dan Aritmatika adalah ratunya matematika". Jadi memahami logika perhitungan sangat esensial untuk menunjang bidang matematika lainnya.

Bagi sebagian orang menganggap bahwa berhitung Mental Aritmatika itu tidak berarti di dunia modern saat ini. Penggunaan kalkulator dan komputer kenyataannya membuat otak manusia jarang digunakan. Untuk itu perlunya pemberdayaan otak kanan dan otak kiri melalui perhitungan kreatif seperti Jarimatika ini. Pada perhitungan dengan menggunakan jari, anak dituntut untuk berimajinasi, analisa, berfikir logika dan membutuhkan daya ingat. Sebagaimana Manfaat Mental Aritmatika yang dibahas dalam tulisan Manfaat Belajar Mental Aritmatika nampaknya akan menarik anda untuk belajar atau mengajarkan kepada anak usia dini demi menumbuhkembangkan daya imajinasi dan logika berfikir yang benar dan analisis.

Pada pendidikan aritmatika, anak diajarkan berhitung dengan menggunakan jari dan kemudian pada tahap selanjutnya tidak perluh harus memperagakan jika seorang anak tersebut telah mampu berhitung dalam kepala. Jika anak telah mampu berhitung bilangan dari 1 sampai 99 maka untuk berhitung selanjutnya dengan menggunakan angka ratusan, ribuan dan jutaan tidak lagi menjadi persoalan.

Bagaimana, anda tertarik? Jangan beranjak dulu, luangkan waktu anda untuk membaca Penjumlahan dan Pengurangan dengan Jari. Terimahkasi!
