The purposes of this research are: (1) the influence of learning motivation on mathematics learning achievement of fifth grade students of Advent 1 Tikala Manado Elementary School. (2) the influence of learning environment on mathematics learning achievement of fifth grade students of Advent 1 Tikala Manado Elementary School. (3) the influence of learning motivation and learning environment on the mathematics learning achievement of fifth grade students of Advent 1 Tikala Manado Elementary School. This type of research is causal associative research with survey research method. The population in this research were fifth grade students of Advent 1 Tikala Manado Elementary School, totaling 42 students. The sampling technique is the total sampling technique, because the population is less than 100 people so that the entire population is sampled. Methods in data collection (1) using a questionnaire. (2) using the value of the results of the midterm exam in mathematics. Data analysis techniques used are descriptive statistics, normality test, linearity test, hypothesis testing (partial test or t test and simultaneous test or F test). The research findings show that 1) There is a positive influence of Learning Motivation on Mathematics Learning Achievement, 2) There is a positive influence of Learning Environment on Mathematics Learning Achievement. 3) There is an influence of Learning Motivation and Learning Environment together on Mathematics Learning Achievement of fifth grade students of Advent 1 Tikala Manado Elementary School.
