Celebrating Hispanic & Latinx Heritage Month

Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Students

My students are such a mix of backgrounds, but primarily Hispanic as we are 2.2 miles from the U.S.-Mexico international border. Thirteen out of 30 of my students are English language learners, six are special needs, and one quarter are economically disadvantaged. Being in a low-income neighborhood, many of my students struggle with reading at grade level as well as perform well below the standard in mathematics. But that is just the data! They are the most excited, engaged, and happy bunch of individuals. I have behavior challenges, a future astronaut math genius, but mostly kids who cannot seem to make sense of how numbers work together.

My Project

Since a large portion of mathematics instruction in 5th-grade centers around fractions, our students need practice connecting the relationships between partial quantities. Adding, subtracting, multiplying, and dividing becomes tricky when visualizing a fraction model when you just draw it! How much do you understand about the part-to-whole relationship? Not as much as when you cut things or build things with your hands. Trying to connect quantities and values to objects in the real world has been a challenge for my students. LEGO pieces are great because most children have played with them and don't see them as "math." Having physical representations of fractions—a visual and kinesthetic model that they can touch and build—will help my students in the following areas of learning:

My students can build fractions using LEGO blocks with different colors.

For instance, the 1x1 LEGO pieces can be used to represent one half using two 1x1 pieces with two different colors. Increasing the ratio one 1x1 LEGO block at a time allows them to see the progression of numerator and denominator with equivalent fractions.

By connecting the addition and subtraction of unlike denominators, my students can connect smaller parts-to-whole ratios. I noticed last year when teaching this concept that it's difficult to visualize on paper when drawing because there can be a disconnect between the proportions. Seeing and feeling that you cannot physically add a smaller LEGO piece to a larger LEGO piece and have the same number of pieces that make up the whole will help them understand this better!

By connecting the area models of numbers when dividing fractions with different denominators, my students can show how the denominator of the divisor connects with multiplication. (This is a very weird concept to understand so using LEGOs will help.)
