Abstract
This research aims to :（1）analyze the mathematics problems of 4 underachieved children in the "number concept" and "the number of operations".（2）explore the number concept and operation ability of the teaching strategies and the difficulties encountered in the implementation of programs.（3）discuss the students’ change and growth.（4）reflect the teacher’s professional growth. To achieve above purposes, action research was adopted. The enhancing number concept and operation competency program takes 20 periods. There are 4 students participate in this study and the data collected include observation, reflect journals, interviews, worksheets, and checklists. The conclusions were summarized as follows:
I. Four underachieved children have learning difficulties in "number concept" and " number of operation"
II. The teaching strategies and difficulties in the process of conducting the program.
1. Picture books integrated in mathematics teaching strategy is feasible.
（1）Picture books integrated in mathematics teaching can improve the "number concept" of four underachieved children.
（2）Picture books integrated in mathematics teaching can create effective
problem -solving situations in mathematics.
（3）Picture books integrated in the problem-solving teaching can raise levels of problem solving strategies.
（4）Picture books integrated the problem-solving teaching can improve student-teacher interaction.
2. The difficulties of conducting the program and teaching strategies
（1）In the process of implementing the program, the researcher is eager to teach
the children with out noticing whether they can absorb
（2）Children of low achievement in math feel frustrated and anxious because their family can’t help them with homework after school.
（3）Four children are easy to become distracted and unable to concentrate on textbooks for a long time in class, so that paraphrase the math questions in their own words.
III. Students’ change and growth.
a. A firm grasp of the meaning of numbers from 0 ~ 100
b. The recognition of number concept and decimal counting
c. Correctly identification the amount of numbers from 0 ~ 100
d. The understanding of addition and subtraction of numbers from 0 ~20
e. Having the basic ability to calculate numbers from 0 ~ 20 in the form of direct computation
f. Enhance the learning of the two-digit addition and subtraction straight significantly
g. The understanding of the inter-relationship of numbers and the methods of using
addition and subtraction to check the answer
h. The improvement of understanding math questions through grasping the calculation beforehand
IV. The teacher’s reflection and professional growth during the process of this research
1. The progress of using the evaluation tools to diagnosis students’ number concepts
and operation competency, the choice of supplementary teaching materials and the execution of teaching strategies
2. The progress of using the worksheets to improve students’ number concepts and
operation competency
3. Learning the effectiveness of encouragement for children to enforce their learning motivation and confidence
4. The promotion of math teaching and evaluation skills through the collaboration
with other teachers
According to the above conclusions, relative suggestions were provided for the reference of future teaching and researches.
Key words：mathematics underachieved children, number concept,
operation competency.
