312 shows that 25 is greater than 12. 1+8=11-2, illustrates that the sum of 1 and 8, is equal to the difference 11 and 2.
Geometry is the final topic illustrated in the book. The topic has three major subcomponents. Firstly, students are required to understand and construct shapes with several attributes. For instance, a rectangle has four equal sides with four equal angles.
There are eight Mathematical practice standards, as illustrated by the P-12 common core mathematics standards. The standards aim at enhancing the teaching and effective understanding of mathematical concepts (Higgs, 2002). This paper focuses on analyzing the Mathematics practice at the second learning grade. The first standard entails understanding and striving to solve a problem. The grade two students depend on objects and pictures to effectively analyze and solve problems. For example, drawing and counting circle to assist in solving simple sums like 3+5=8. The leaner draws s circles, and then another five circles. The answer is achieved by counting all the eight circles. The second standard entails reasoning quantitatively. Quantitative reasoning involves developing adequate representation of the mathematical problem, analyzing the units involved, and knowing meaning of quantities. Quantitative aspect also entails understanding and flexibly applying several operations properties. 3+1=4, illustrates analysis of the addition unit.
The third standard is making viable arguments, and also critiquing the quantitative opinion of others. The second grade learners have the ability of reasoning inductively concerning data. The students can develop arguments through applying concrete referents like actions, drawings and objects. The students can learn, read and also listen to the arguments of peers and also the teachers. The second grade students can effectively identify a
