Rational Numbers Additive Inverse Compare Order Anchor Chart Example: subtract 1 3 from 1 2. step 1: find the lcm of the denominators of the given rational numbers. in this case, the lcm of 2 and 3 is 6. step 2: convert each rational number into an equivalent rational number with the lcm as the new denominator. 1 × 3 2 × 3 = 3 6 and $1 \times 2} {3 \times 2 = \frac {2} {6}$. 7.ns.a.1.c — understand subtraction of rational numbers as adding the additive inverse, p q = p ( q). show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real world contexts. 7.ns.a.1.d — apply properties of operations as strategies to add and.
How To Compare Rational Numbers Anchor Chart Gameplay instructions. students pick up a card and identify the operation being used. they then apply the inverse operation to verify the result. for instance, if a card displays ‘4 3 = 7’, the student identifies the operation as addition. the inverse operation (subtraction) is applied to check the result: ‘7 – 3 = 4’. 7.ns.a.1.b — understand p q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. show that a number and its opposite have a sum of 0 (are additive inverses). interpret sums of rational numbers by describing real world contexts. The additive identity property: the rational number 0 acts as an identity of addition. this means that, for any rational number 𝑎 𝑏, we must have 𝑎 𝑏 0 = 0 𝑎 𝑏 = 𝑎 𝑏. in other words, addition by 0 leaves rational numbers unchanged. the commutativity property: the sum of rational numbers is commutative. Created by. magnolia math academy. this bright and fun colored anchor chart makes learning comparing and ordering numbers fun and practical. you can use the poster during small group, circle time, whole group, or as a visual on the wall for independent work.this poster is for upper elementary students.
