1.MD.2. Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps. Limit to contexts where the object being measured is spanned by a whole number of length units with no gaps or overlaps.||Common Core Mathematics||Grade 1||Measurement And Data||Measure Lengths Indirectly And By Iterating Length Units|||2.MD.1. Measure the length of an object by selecting and using appropriate tools such as rulers, yardsticks, meter sticks, and measuring tapes.||Common Core Mathematics||Grade 2||Measurement And Data||Measure And Estimate Lengths In Standard Units|||4.MD.1. Know relative sizes of measurement units within one system of units including km, m, cm; kg, g; lb, oz.; l, ml; hr, min, sec. Within a single system of measurement, express measurements in a larger unit in terms of a smaller unit. Record measurement equivalents in a two- column table. For example, know that 1 ft is 12 times as long as 1 in. Express the length of a 4 ft snake as 48 in. Generate a conversion table for feet and inches listing the number pairs (1, 12), (2, 24), (3, 36), …||Common Core Mathematics||Grade 4||Measurement And Data||Solve Problems Involving Measurement And Conversion Of Measurements From A Larger Unit To A Smaller Unit
