People have to start from the ground, then first step, second, third and so on to reach their destination floor. Exactly the same way students have to start from Kindergarten, then grade one, grade two and three and so on to reach their math destination. Also, if some of the steps are broken in the staircase, it is still hard to reach the desired floor using those steps. Same way, if you are missing some of the basic concepts from elementary grades, math for you is still hard. Now, the kindergarten, first grade and second grade are like first couple of the steps of the stairs. You can learn this level of math easily, as you can jump enough to take yourself to second or third step of the stairs easily. As it is very hard to reach sixth or seventh step of a stairs by jumping from the ground, exactly the same way to learn grade five or higher grade math is very hard (or impossible) without having the good knowledge of the kindergarten to grade three or grade four math. Now, consider one person is jumping on the ground to reach the third floor of a building. Can this person make it? Never, if he is not Spiderman. For this person, to reach the third floor by jumping is impossible or very hard and finally he gave up saying that it was very hard to reach third floor.
Math worksheets don't promote communication and collaboration _ Math worksheets are often assigned as an independent activity, however research indicates that communication and discourse are needed to build a deep understanding of math topics. Students need opportunities to explore mathematical ideas in different ways and to build their own connections. This involves communicating their ideas, listening to the ideas of others, arguing a viewpoint, describing, and explaining. Math worksheets are rarely used as a catalyst for conversation. Instead of assigning worksheets, find activities that encourage discourse, such as "number talks," or collaborative group work. During the session, be sure to require students to explain their thinking and listen to the strategies and thinking of their peers. If you are fortunate enough to have an interactive whiteboard in your classroom, using it with interactive math software creates many opportunities for group discussion and student participation. Teachers can can begin by posing problems and modeling approaches, and then ask students to work together to find solutions. Then have them come to the board to demonstrate their solutions in front of the class. These days, many examples of how to teach math concepts on an interactive whiteboard can be found online in the various whiteboard community sites, educational sites, YouTube, etc.
