One of the first parts to teaching part part whole is the unknown; the question. Students should have a lot of exposure with unknowns of varying types- variables, question marks, blank lines, boxes, etc to build the understanding that they all represent the same thing. It’s imperative that the unknown is in varying positions- especially to the left...
Addition is putting parts together to find the total, or whole. Children build this understanding by counting groups of objects together to find their total. Students explore sums using manipulatives and build their understanding of addition, and their facts as well, through hands-on explorations. One of my favorite tools to model addition for stud...
Subtraction is taking the whole and splitting into parts. This understanding is built in the same way as addition- through exploration with groups of objects. Giving students a group of objects to split into smaller parts helps build this understanding. The work with the base ten cubes or linking cubes above helps students see that the same total o...
Teaching fact families should also be rooted in part part whole. Fact family triangles help students visually see part and whole relationships. When teaching fact families I use the house representation pictured below. I always put addition and subtraction equations as related to part and whole in the triangle for the roof to help keep students foc...
There are many different models for part-part-whole relationships. Two of the most common are bar models and number bonds. I find bar models to be the most helpful when working with word problems as students can visually see the parts relating to the whole and which portion is the unknown. Number bonds, in my opinion, are more relevant when looking...
Students’ understanding of addition, subtraction, and part-part-whole is evident through their understanding of word problems. Through story problems, students demonstrate they can use the context to determine the operation being used and can apply it independently. To specifically practice part-part-whole scenarios, I have these Part-Part-Whole Di...
In addition to teaching part-part-whole with my students, I also teach start-change-end with addition and subtraction. In real world scenarios, addition and subtraction is either (or sometimes both) start-change-end or part-part-whole. I teach both explicitly with my 1st and 2nd graders and we talk about our word problems in relation to both. You c...
As a third grade teacher, when I introduce students to multiplication and division I relate it back to part-part-whole. We change the “part” to “# of groups” and “# in each group”. If students have a solid understanding of parts and whole they understand the multiplication and division relationship much more easily when it’s introduced and connecte...
Once students have a solid understanding of part-part-whole and start-change-end scenarios, we continue to build their addition and subtraction mastery and fact fluency through ongoing play and practice. I love to use games and centers to build my students’ addition and subtraction fact fluency because students don’t feel the stress they do in time...
Decompose a number Decomposing a number means taking a whole number and breaking it into two smaller parts. To decompose the number 5, you can break it into smaller parts of 4 and 1, or 3 and 2. A number bond is a tool you can use to show parts of a whole. A number bond has one circle on top and two circles on the bottom.
Sep 23, 2024 · Read more: What is a bar model. The act of splitting a number into component parts is known as partitioning. The part-whole model is a useful model for students to learn and utilize as it will assist with addition and subtraction later on in their mathematical journey. A fraction bar model and bar model multiplication and division will also be ...
Line DEFINE. A straight object that goes on forever in two directions; it has a length, but no width. Ray DEFINE. A straight object that starts at a point and goes on forever in one direction, shown by an arrow. Parallel DEFINE. Two lines that always stay the same distance apart. Perpendicular DEFINE. Two lines that intersect at a 90-degree ...
- Showing where something is; earning credit for getting something right; a dot; a mark on a line plot or other data display.
- Rectangular tabletops, floors, or walls; circular clock; triangular pennants.
- The top and bottom of a brick; the top of one wall and the bottom of another.
- Any closed shape with 4 straight sides, where the sides do not connect at all 90-degree angles is correct.
- Students may point out the corners of their desk, or of the floor tiles.
- In daily life, lines may be curved or stop, but as a mathematical object lines need to be straight and go on forever.
- The sides have a starting point and an ending point. They are line segments.
- Sides of rectangular objects; sides of triangles that meet at a 90-degree angle.
- For example, a square has 2 pairs of parallel sides and 4 pairs of perpendicular sides.
- Yes, as long as they cross somewhere so they share a point, rays or lines could form angles.
