How Many Marbles Does Joe's Friends Have?
1. The four different models we can use for teaching multiplication concepts are sets of objects, arrays, number lines, and grid charts.
-Sets of objects are used to solve problems that involve groups where each group has the same number of objects. For example: Joe has 5 friends, and each of his friends has 5 marbles. How many marbles does Joe’s friends have? To solve this problem, you can draw it out as 5 different groups and each group has five marbles each. Answer: Joe’s friends have 25 marbles all together.

-Number lines can be used to solve multiplication problems by skip hopping to the number you are multiplying and then the number of hops is the other side of the problem. Once you hop the number of times then the last number is

    The development of mathematical learning and understanding, through a variety of different techniques and strategies, is particularly significant. One of the crucial early learning ideas associated with number is the connection between language, symbols and materials (Larkin, 2013a). Booker et al. (2010) states that language is a key aspect to mathematical learning from the conceptual formation of processing and problem-solving, to the development of numerate students. The Language Model For Mathematics - See Figure 1 (Larkin, 2013b), is purpose built around this idea. It emphasises that when teaching mathematics teachers should progress from the…

    Numbers can get really large and hard to manage. For example 53000000*69000000 would end up as a huge number to be written out. Now if you write it as 5.3*10^7*6.9*10^7 makes it much simpler of a problem which the answer would be 3.657*10^14…

    Understanding that multiplication and repeated addition are related will help extend the students use of multiplication. They will understand that when grouping items they can use multiplication to achieve the same answer in a shorter amount of time. One method I can use to teach repeat addition and multiplication is manipulatives. For example, I can use a projector to display a picture of a box and two small toy kittens. I will start out with one box with one group of kittens. I will progress to display two groups with two toy kittens each. This will continue for however far I see fit. I will model how multiplication is a form of repeated addition. I will write the written form of addition and multiplication next to each problem. By the group of two toy kittens I will write out 1+1=2 and 2*1=2 on the white board display. For the group of two boxes with two kittens in each group I will write 2+2=4 and 2*2=4 on the white board display. Understanding the basic principles and properties for addition and multiplication is key for later skills with algebraic equations. By understanding the properties of multiplication, this will help them figure out grouped items as well as word problems. The understanding of this concept also helps with the understanding in comparison problems. Area calculation is another extent that understanding multiplication and addition will help in mathematics.…

    I currently teach a second grade class, but I have learned valuable information that I can use to help prepare my students mathematically for third grade. In second grade, my class completes tasks focusing on arrays and repeated addition toward the end of the school year. Creating equal groups is another concept taught more toward the end of the year. This course has provided insight on the importance making connections between mathematical operations: addition, subtraction, multiplication, and division. Another skill taught in second grade is decomposing numbers into hundreds, tens, and ones as students write numbers in expanded form or use base ten blocks to create a visual representation of a number. Students will continue to decompose numbers as they transition from addition and subtraction to multiplication and division (Beckman, 2014a, p.316). Completing assignments for grades higher than…
