Math Balance can be purchased standalone, or as part of a makkajai Genius subscription. Fluently add and subtract within 1000 using strategies and algorithms based on place value properties of operations, and/or the relationship between addition and subtractionįor those who follow the Core curriculum, this maps to the following core standards - 2.OA.B.2, 2.NBT.4, 2.OA.2, 1.OA.6, 2.OA.C.3, 2.OA.1, 2.NBT.6, 2.NBT.7, 2.NBT.8, 3.NBT.2. Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900 Using concrete models to show addition and subtraction add a string of two-digit numbers (up to four numbers) by applying place value strategies and properties of operations. 1 step word problems -Change unknown, Result unknown, Start unknown Use only doubles, Use only even/odd numbers to get to a total Showing that addition and subtraction are inverse 4+5=9, 9-5=4 Missing Addend strategies:x+b=c, where x is to be found, situations where difference is unknown, where there is a bigger unknown and where there is a smaller unknown -one step problems Commutative property of addition and, later, using it and expanded form as a strategy to add ex: 67+25 = 60+7+20+5 = 80+12 =92 Developing meaning of equal sign, using, greater than and less than sign These are the skills covered by Math Balance. They will also end up having to use different number strategies, such as bridging and compensation which can significantly speed up their mental math computations. Your child will learn things like addition can happen in any order for the same result, or that sum of different numbers can add up to be the same number. This mental math game with 30 levels will help your child get necessary fluidity with numbers.
Mental Math is fun with Math Balance - kids help Toby reach home by balancing bridges and while they have fun, they also learn about equality/comparison, gain flexibility with numbers and practice skills that are essential for understanding algebra.
