Numeracy is an individual's ability to reason mathematically, formulate, use, and interpret mathematics to solve problems in a variety of real-life contexts. Through the implementation of the Merdeka Curriculum, numeracy skills are tested on students through the Minimum Competency Assessment (AKM) instrument. The numeracy skills tested in the AKM contain four domains in mathematics, namely number, algebra, geometry and measurement, and data and uncertainty. The results of the AKM are used to improve the quality of learning and mapping the quality of learning in each education unit. Facts in the field show that the importance of numeracy skills is not directly proportional to the results of surveys from various institutions regarding the numeracy skills of students in Indonesia. Based on the PISA results, the numeracy skills of Indonesian students are still below the average international numeracy skills. This gap occurs because the learning system in Indonesia is not accustomed to giving numeracy problems. One of the factors that cause the low numeracy skills of Indonesian students is that not all teachers or prospective mathematics teachers know about numeracy problems and use them in learning. It should be realized that prospective mathematics teachers are the next generation of Indonesian mathematics education that must be well prepared. Prospective mathematics teachers must have good knowledge and competence in numeracy problems. If traced further, there has been no research that specifically discusses the development of numeracy worksheets that are focused on improving the mathematical adaptive reasoning skills of prospective mathematics teachers. So far, research in the field of education still focuses a lot on students as the subject of research. Departing from the curiosity about the numeracy skills of prospective mathematics teachers, a preliminary study was conducted with 13 prospective mathematics teachers. From this activity, it was found that their numeracy skills were still relatively low. Therefore, real efforts are needed to improve the ability of teachers, one of which is by introducing and familiarizing numeracy problems. Numeracy mastery is in line with the level of mathematical adaptive reasoning ability. Adaptive reasoning refers to the ability to think logically about the relationship between concepts and situations. Numeracy mastery and mathematical adaptive reasoning ability can be improved through giving numeracy problems. This can be done by digitizing worksheets. One of the platforms that can be used to develop digital worksheets is Liveworksheet. The purpose of this research is to produce a Liveworksheet of numeracy problems to improve mathematical adaptive reasoning skills, as well as to describe the validity, practicality, and effectiveness of the Liveworksheet. The numeracy problems developed are at the cognitive level of reasoning. Each problem will contain indicators of mathematical adaptive reasoning ability and indicators of the material used. The domain that becomes the main topic in the development of the worksheet is number and geometry. The development method used is ADDIE, which consists of analyze, design, development, implementation, and evaluation. The subjects of this study were 40 prospective mathematics teacher students. The research instruments used in this study include material expert validation sheets, learning media expert validation sheets, user response questionnaires, pre test sheets, and post test sheets. The results of the assessment of material experts and learning media experts show that the developed Liveworksheet is valid to be given to the research subjects. The results of the user response questionnaire assessment show that the developed Liveworksheet is in the practical category. In line with this, the results of the paired data t-test showed that the Liveworksheet has an influence on improving the adaptive reasoning ability of mathematics teacher candidates. Furthermore, the level of effectiveness achieved based on the average N-gain score is quite effective.
