Christian Living

In this grade level, the students will learn and appreciate God’s creation; all that God makes is good and he shows his goodness, love and presence with us. Jesus sends us the Holy Spirit to be our helper and our guide in our fight against temptation. At the heart of the Old Testament is the commandment to love God with all our heart, soul, and strength. The old covenant consisted of over 600 laws, governing every aspect of life. Among them was the command to love one’s neighbor as oneself. Jesus, the living embodiment of the law, elevated love of neighbor to an essential condition on which our love of God depends. He summed up the whole law in this-the love of God and that of our neighbor is intertwined. Love of neighbor is our response to the love of God for us. The promises of the Beatitudes flesh out the Great Commandment. The Beatitudes teach that happiness comes to those who place their trust in God rather than in power, possessions, or pleasures. It reflects the way Jesus lived. The students are attracted to the ideals of fairness and happiness described by the Beatitudes. They will appreciate that their efforts can help bring peace, justice, and caring to their world.


Language Arts


The language arts curriculum includes objectives that support students’ development in the skills of writing, listening, and oral language. The grade 4 Reading program aims at establishing good reading habits while developing comprehension strategies and vocabulary. The students will be introduced to approaches to analyze texts appropriate to their level when reading fiction and non-fiction books confidently, fluently, and independently.  These skills are developed through explicit instruction and guided practice. Through daily classroom experiences, the children will write fluently and effectively and they will use speech responsibly to inform, entertain, and influence others. They will be able to listen for a sustained period of time and for a variety of purposes. Pupils will use a wide range of vocabulary and complex sentence structures to clearly express and explain their thoughts, needs, feelings, opinions and ideas.







Grade 4 Math provides more activities that will develop further the acquisition of mathematical concepts and skills learned in the previous grades. The lessons built in the context of life-related situations help students retain and apply theories they learn. Basic operations deal with larger whole numbers and decimals, like and unlike fractions, and use simple formulas to solve problems in geometry.




The Science course for Fourth grade has been developed to reflect real world situations through the use of hands-on opportunities for learning.  Learning Science, at this stage, is not necessarily about memorizing the “right answers” but rather about the process of asking questions, solving problems, and making decisions based on the information gathered. The aim of the course is to lay a helpful foundation for the correct interpretation of results based upon scientific observations.


Social Studies


The Social Studies course for Grade 4 has been designed to help students build geography skills and an understanding of the world they live in. Students will also be motivated to find out historical facts and to discover the true meaning of responsible citizenship.

    • Math.Content.4.NF.B.4bUnderstand a multiple of a/b as a multiple of 1/b, and use this understanding to multiply a fraction by a whole number. For example, use a visual fraction model to express 3 × (2/5) as 6 × (1/5), recognizing this product as 6/5. (In general, n × (a/b) = (n × a)/b.)
    • Math.Content.4.NF.B.4cSolve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent the problem. For example, if each person at a party will eat 3/8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?

  • Math.Content.4.NF.C.5Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.2For example, express 3/10 as 30/100, and add 3/10 + 4/100 = 34/100.
  • Math.Content.4.NF.C.6Use decimal notation for fractions with denominators 10 or 100. For example, rewrite 0.62 as 62/100; describe a length as 0.62 meters; locate 0.62 on a number line diagram.
  • Math.Content.4.NF.C.7Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole.

Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two-column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), …
  • Math.Content.4.MD.A.2Use the four operations to solve word problems involving distances, intervals of time, liquid volumes, masses of objects, and money, including problems involving simple fractions or decimals, and problems that require expressing measurements given in a larger unit in terms of a smaller unit. Represent measurement quantities using diagrams such as number line diagrams that feature a measurement scale.
  • Math.Content.4.MD.A.3Apply the area and perimeter formulas for rectangles in real world and mathematical problems. For example, find the width of a rectangular room given the area of the flooring and the length, by viewing the area formula as a multiplication equation with an unknown factor.

Represent and interpret data.

  • Math.Content.4.MD.B.4Make a line plot to display a data set of measurements in fractions of a unit (1/2, 1/4, 1/8).

Geometric measurement: understand concepts of angle and measure angles.

  • Math.Content.4.MD.C.5Recognize angles as geometric shapes that are formed wherever two rays share a common endpoint, and understand concepts of angle measurement:
    • Math.Content.4.MD.C.5aAn angle is measured with reference to a circle with its center at the common endpoint of the rays, by considering the fraction of the circular arc between the points where the two rays intersect the circle. An angle that turns through 1/360 of a circle is called a “one-degree angle,” and can be used to measure angles.
    • Math.Content.4.MD.C.5bAn angle that turns through n one-degree angles is said to have an angle measure of n degrees.
  • Math.Content.4.MD.C.6Measure angles in whole-number degrees using a protractor. Sketch angles of specified measure.
  • Math.Content.4.MD.C.7Recognize angle measure as additive. When an angle is decomposed into non-overlapping parts, the angle measure of the whole is the sum of the angle measures of the parts.
